backuplbmethod

ROUNDROBIN
LEASTCONNECTION
LEASTRESPONSETIME
SOURCEIPHASH
LEASTBANDWIDTH
LEASTPACKETS
CUSTOMLOAD

Backup load balancing method. Becomes operational if the primary load balancing me

thod fails or cannot be used.

Valid only if the primary method is based on static proximity.

backuppersistencetimeout

Time period for which backup persistence is in effect.

Minimum value = 2

Maximum value = 1440

bypassaaaa

If this option is enabled while resolving DNS64 query AAAA queries are not sent to back end dns server.

cacheable

Route cacheable requests to a cache redirection virtual server. The load balancing virtual server can forward requests only to a transparent cache redirection virtual server that has an IP address and port combination of *:80, so such a cache redirection virtual server must be configured on the appliance.

Maximum value = 31536000

comment

Any comments that you might want to associate with the virtual server.

connfailover

DISABLED
STATEFUL
STATELESS

Mode in which the connection failover feature must operate for the virtual server. After a failover, established TCP connections and UDP packet flows are kept active and resumed on the secondary appliance. Clients remain connected to the same servers. Available settings function as follows:

* STATEFUL - The primary appliance shares state information with the secondary appliance, in real time, resulting in some runtime processing overhead.

* STATELESS - State information is not shared, and the new primary appliance tries to re-create the packet flow on the basis of the information contained in the packets it receives.

* DISABLED - Connection failover does not occur.

cookiename

Use this parameter to specify the cookie name for COOKIE peristence type. It specifies the name of cookie with a maximum of 32 characters. If not specified, cookie name is internally generated.

datalength

Length of the token to be extracted from the data segment of an incoming packet, for use in the token method of load balancing. The length of the token, specified in bytes, must not be greater than 24 KB. Applicable to virtual servers of type TCP.

Minimum value = 1

Maximum value = 100

dataoffset

Offset to be considered when extracting a token from the TCP payload. Applicable to virtual servers, of type TCP, using the token method of load balancing. Must be within the first 24 KB of the TCP payload.

Minimum value = 0

Maximum value = 25400

dbprofilename

Name of the DB profile whose settings are to be applied to the virtual server.

disabled

When set to yes the lb vserver will be disabled.

When set to no the lb vserver will be enabled.

Note that due to limitations of the underlying NITRO API a disabled state change alone does not cause the module result to report a changed status.

disableprimaryondown

enabled
disabled

If the primary virtual server goes down, do not allow it to return to primary status until manually enabled.

dns64

enabled
disabled

This argument is for enabling/disabling the dns64 on lbvserver.

dnsprofilename

Name of the DNS profile to be associated with the VServer. DNS profile properties will be applied to the transactions processed by a VServer. This parameter is valid only for DNS and DNS-TCP VServers.

Minimum length = 1

Maximum length = 127

downstateflush

disabled

Flush all active transactions associated with a virtual server whose state transitions from UP to DOWN. Do not enable this option for applications that must complete their transactions.

hashlength

Number of bytes to consider for the hash value used in the URLHASH and DOMAINHASH load balancing methods.

Minimum value = 1

Maximum value = 4096

healththreshold

Threshold in percent of active services below which vserver state is made down. If this threshold is 0, vserver state will be up even if one bound service is up.

Minimum value = 0

Maximum value = 100

httpprofilename

Name of the HTTP profile whose settings are to be applied to the virtual server.

Minimum length = 1

Maximum length = 127

icmpvsrresponse

PASSIVE
ACTIVE

How the NetScaler appliance responds to ping requests received for an IP address that is common to one or more virtual servers. Available settings function as follows:

* If set to PASSIVE on all the virtual servers that share the IP address, the appliance always responds to the ping requests.

* If set to ACTIVE on all the virtual servers that share the IP address, the appliance responds to the ping requests if at least one of the virtual servers is UP. Otherwise, the appliance does not respond.

* If set to ACTIVE on some virtual servers and PASSIVE on the others, the appliance responds if at least one virtual server with the ACTIVE setting is UP. Otherwise, the appliance does not respond.

Note: This parameter is available at the virtual server level. A similar parameter, ICMP Response, is available at the IP address level, for IPv4 addresses of type VIP. To set that parameter, use the add ip command in the CLI or the Create IP dialog box in the GUI.

insertvserveripport

OFF
VIPADDR
V6TOV4MAPPING

Insert an HTTP header, whose value is the IP address and port number of the virtual server, before forwarding a request to the server. The format of the header is <vipHeader>: <virtual server IP address>_<port number >, where vipHeader is the name that you specify for the header. If the virtual server has an IPv6 address, the address in the header is enclosed in brackets ([ and ]) to separate it from the port number. If you have mapped an IPv4 address to a virtual server's IPv6 address, the value of this parameter determines which IP address is inserted in the header, as follows:

* VIPADDR - Insert the IP address of the virtual server in the HTTP header regardless of whether the virtual server has an IPv4 address or an IPv6 address. A mapped IPv4 address, if configured, is ignored.

* V6TOV4MAPPING - Insert the IPv4 address that is mapped to the virtual server's IPv6 address. If a mapped IPv4 address is not configured, insert the IPv6 address.

* OFF - Disable header insertion.

ipmask

IP mask, in dotted decimal notation, for the IP Pattern parameter. Can have leading or trailing non-zero octets (for example, 255.255.240.0 or 0.0.255.255). Accordingly, the mask specifies whether the first n bits or the last n bits of the destination IP address in a client request are to be matched with the corresponding bits in the IP pattern. The former is called a forward mask. The latter is called a reverse mask.

ippattern

IP address pattern, in dotted decimal notation, for identifying packets to be accepted by the virtual server. The IP Mask parameter specifies which part of the destination IP address is matched against the pattern. Mutually exclusive with the IP Address parameter.

For example, if the IP pattern assigned to the virtual server is 198.51.100.0 and the IP mask is 255.255.240.0 (a forward mask), the first 20 bits in the destination IP addresses are matched with the first 20 bits in the pattern. The virtual server accepts requests with IP addresses that range from 198.51.96.1 to 198.51.111.254. You can also use a pattern such as 0.0.2.2 and a mask such as 0.0.255.255 (a reverse mask).

If a destination IP address matches more than one IP pattern, the pattern with the longest match is selected, and the associated virtual server processes the request. For example, if virtual servers vs1 and vs2 have the same IP pattern, 0.0.100.128, but different IP masks of 0.0.255.255 and 0.0.224.255, a destination IP address of 198.51.100.128 has the longest match with the IP pattern of vs1. If a destination IP address matches two or more virtual servers to the same extent, the request is processed by the virtual server whose port number matches the port number in the request.

ipv46

IPv4 or IPv6 address to assign to the virtual server.

l2conn

Use Layer 2 parameters (channel number, MAC address, and VLAN ID) in addition to the 4-tuple (<source IP>:<source port>::<destination IP>:<destination port>) that is used to identify a connection. Allows multiple TCP and non-TCP connections with the same 4-tuple to co-exist on the NetScaler appliance.

lbmethod

ROUNDROBIN
LEASTCONNECTION
LEASTRESPONSETIME
URLHASH
DOMAINHASH
DESTINATIONIPHASH
SOURCEIPHASH
SRCIPDESTIPHASH
LEASTBANDWIDTH
LEASTPACKETS
TOKEN
SRCIPSRCPORTHASH
LRTM
CALLIDHASH
CUSTOMLOAD
LEASTREQUEST
AUDITLOGHASH
STATICPROXIMITY

Load balancing method. The available settings function as follows:

* ROUNDROBIN - Distribute requests in rotation, regardless of the load. Weights can be assigned to services to enforce weighted round robin distribution.

* LEASTCONNECTION (default) - Select the service with the fewest connections.

* LEASTRESPONSETIME - Select the service with the lowest average response time.

* LEASTBANDWIDTH - Select the service currently handling the least traffic.

* LEASTPACKETS - Select the service currently serving the lowest number of packets per second.

* CUSTOMLOAD - Base service selection on the SNMP metrics obtained by custom load monitors.

* LRTM - Select the service with the lowest response time. Response times are learned through monitoring probes. This method also takes the number of active connections into account.

Also available are a number of hashing methods, in which the appliance extracts a predetermined portion of the request, creates a hash of the portion, and then checks whether any previous requests had the same hash value. If it finds a match, it forwards the request to the service that served those previous requests. Following are the hashing methods:

* URLHASH - Create a hash of the request URL (or part of the URL).

* DOMAINHASH - Create a hash of the domain name in the request (or part of the domain name). The domain name is taken from either the URL or the Host header. If the domain name appears in both locations, the URL is preferred. If the request does not contain a domain name, the load balancing method defaults to LEASTCONNECTION.

* DESTINATIONIPHASH - Create a hash of the destination IP address in the IP header.

* SOURCEIPHASH - Create a hash of the source IP address in the IP header.

* TOKEN - Extract a token from the request, create a hash of the token, and then select the service to which any previous requests with the same token hash value were sent.

* SRCIPDESTIPHASH - Create a hash of the string obtained by concatenating the source IP address and destination IP address in the IP header.

* SRCIPSRCPORTHASH - Create a hash of the source IP address and source port in the IP header.

* CALLIDHASH - Create a hash of the SIP Call-ID header.

listenpolicy

Default syntax expression identifying traffic accepted by the virtual server. Can be either an expression (for example, CLIENT.IP.DST.IN_SUBNET(192.0.2.0/24) or the name of a named expression. In the above example, the virtual server accepts all requests whose destination IP address is in the 192.0.2.0/24 subnet.

listenpriority

Integer specifying the priority of the listen policy. A higher number specifies a lower priority. If a request matches the listen policies of more than one virtual server the virtual server whose listen policy has the highest priority (the lowest priority number) accepts the request.

Minimum value = 0

Maximum value = 101

IP
MAC
IPTUNNEL
TOS

Redirection mode for load balancing. Available settings function as follows:

* IP - Before forwarding a request to a server, change the destination IP address to the server's IP address.

* MAC - Before forwarding a request to a server, change the destination MAC address to the server's MAC address. The destination IP address is not changed. MAC-based redirection mode is used mostly in firewall load balancing deployments.

* IPTUNNEL - Perform IP-in-IP encapsulation for client IP packets. In the outer IP headers, set the destination IP address to the IP address of the server and the source IP address to the subnet IP (SNIP). The client IP packets are not modified. Applicable to both IPv4 and IPv6 packets.

* TOS - Encode the virtual server's TOS ID in the TOS field of the IP header.

You can use either the IPTUNNEL or the TOS option to implement Direct Server Return (DSR).

newservicerequest

Number of requests, or percentage of the load on existing services, by which to increase the load on a new service at each interval in slow-start mode. A non-zero value indicates that slow-start is applicable. A zero value indicates that the global RR startup parameter is applied. Changing the value to zero will cause services currently in slow start to take the full traffic as determined by the LB method. Subsequently, any new services added will use the global RR factor.

persistencetype

SOURCEIP
COOKIEINSERT
SSLSESSION
RULE
URLPASSIVE
CUSTOMSERVERID
DESTIP
SRCIPDESTIP
CALLID
RTSPSID
DIAMETER
FIXSESSION
NONE

Type of persistence for the virtual server. Available settings function as follows:

* SOURCEIP - Connections from the same client IP address belong to the same persistence session.

* COOKIEINSERT - Connections that have the same HTTP Cookie, inserted by a Set-Cookie directive from a server, belong to the same persistence session.

* SSLSESSION - Connections that have the same SSL Session ID belong to the same persistence session.

* CUSTOMSERVERID - Connections with the same server ID form part of the same session. For this persistence type, set the Server ID (CustomServerID) parameter for each service and configure the Rule parameter to identify the server ID in a request.

* RULE - All connections that match a user defined rule belong to the same persistence session.

* URLPASSIVE - Requests that have the same server ID in the URL query belong to the same persistence session. The server ID is the hexadecimal representation of the IP address and port of the service to which the request must be forwarded. This persistence type requires a rule to identify the server ID in the request.

* DESTIP - Connections to the same destination IP address belong to the same persistence session.

* SRCIPDESTIP - Connections that have the same source IP address and destination IP address belong to the same persistence session.

* CALLID - Connections that have the same CALL-ID SIP header belong to the same persistence session.

pushvserver

Name of the load balancing virtual server, of type PUSH or SSL_PUSH, to which the server pushes updates received on the load balancing virtual server that you are configuring.

Minimum length = 1

range

Number of IP addresses that the appliance must generate and assign to the virtual server. The virtual server then functions as a network virtual server, accepting traffic on any of the generated IP addresses. The IP addresses are generated automatically, as follows:

* For a range of n, the last octet of the address specified by the IP Address parameter increments n-1 times.

* If the last octet exceeds 255, it rolls over to 0 and the third octet increments by 1.

Note: The Range parameter assigns multiple IP addresses to one virtual server. To generate an array of virtual servers, each of which owns only one IP address, use brackets in the IP Address and Name parameters to specify the range. For example:

add lb vserver my_vserver[1-3] HTTP 192.0.2.[1-3] 80.

Minimum value = 1

Maximum value = 254

recursionavailable

When set to YES, this option causes the DNS replies from this vserver to have the RA bit turned on. Typically one would set this option to YES, when the vserver is load balancing a set of DNS servers thatsupport recursive queries.

redirectportrewrite

enabled
disabled

Rewrite the port and change the protocol to ensure successful HTTP redirects from services.

redirurl

URL to which to redirect traffic if the virtual server becomes unavailable.

WARNING! Make sure that the domain in the URL does not match the domain specified for a content switching policy. If it does, requests are continuously redirected to the unavailable virtual server.

Minimum length = 1

resrule

Default syntax expression specifying which part of a server's response to use for creating rule based persistence sessions (persistence type RULE). Can be either an expression or the name of a named expression.

Example:

HTTP.RES.HEADER("setcookie".VALUE(0).TYPECAST_NVLIST_T('=',';').VALUE("server1")).

rhistate

PASSIVE
ACTIVE

Route Health Injection (RHI) functionality of the NetSaler appliance for advertising the route of the VIP address associated with the virtual server. When Vserver RHI Level (RHI) parameter is set to VSVR_CNTRLD, the following are different RHI behaviors for the VIP address on the basis of RHIstate (RHI STATE) settings on the virtual servers associated with the VIP address:

* If you set rhistate to PASSIVE on all virtual servers, the NetScaler ADC always advertises the route for the VIP address.

* If you set rhistate to ACTIVE on all virtual servers, the NetScaler ADC advertises the route for the VIP address if at least one of the associated virtual servers is in UP state.

* If you set rhistate to ACTIVE on some and PASSIVE on others, the NetScaler ADC advertises the route for the VIP address if at least one of the associated virtual servers, whose rhistate set to ACTIVE, is in UP state.

rtspnat

Use network address translation (NAT) for RTSP data connections.

somethod

CONNECTION
DYNAMICCONNECTION
BANDWIDTH
HEALTH
NONE

Type of threshold that, when exceeded, triggers spillover. Available settings function as follows:

* CONNECTION - Spillover occurs when the number of client connections exceeds the threshold.

* DYNAMICCONNECTION - Spillover occurs when the number of client connections at the virtual server exceeds the sum of the maximum client (Max Clients) settings for bound services. Do not specify a spillover threshold for this setting, because the threshold is implied by the Max Clients settings of bound services.

* BANDWIDTH - Spillover occurs when the bandwidth consumed by the virtual server's incoming and outgoing traffic exceeds the threshold.

* HEALTH - Spillover occurs when the percentage of weights of the services that are UP drops below the threshold. For example, if services svc1, svc2, and svc3 are bound to a virtual server, with weights 1, 2, and 3, and the spillover threshold is 50%, spillover occurs if svc1 and svc3 or svc2 and svc3 transition to DOWN.

* NONE - Spillover does not occur.
