2 To create an IPv4 cluster node for Intelligent Traffic Director (ITD), use the command. To remove the cluster node, use the no form of this command. ipv4-address [mode hot-standby] [standby ipv4-address] [weight value] no ipv4-address [mode hot-standby] [standby ipv4-address] [weight value] Syntax Description ipv4-address mode hot-standby standbyipv4-address weight value IPv4 address for the node. (Optional) Specifies that the node is a standby node for any active node member of the device group. (Optional) Specifies that the node is a standby for the active node. (Optional) Specifies proportionate weight for the node for weighted traffic distribution. Command Default None. Command Modes Device group configuration (config-device-group) Command History Release 6.2(10) 6.2(8) Modification The following keywords and arguments were added: standby ipv4-address and weight value. This command was introduced. Usage Guidelines You must ensure that ITD is enabled before you enter this command. You can enter the feature itd global configuration mode command to enable ITD. The ip-address mode hot-standby command allows you to specify that a particular node is the standby node if a failure occurs. ITD redirects traffic away from the failed node to the newly active (standby) node. When the failed node becomes operational again, it is reinstated as an active node and traffic from the standby node is redirected back to the original node. The standby node reenters the pool of standby nodes. The ipv4-address standby ipv4-address command allows you to specify that a particular node is the standby node for the active node with which it is associated. 2
3 An ITD device group can have either IPv4 or IPv6 nodes, but not both. Before modifying the service parameters or device-group parameters, you must enter the shutdown command. Once the required parameters are modified, you should enter the no shutdown command on the service. This command requires the Enhanced Layer 2 Package license. Examples This example shows how to configure IPv4 nodes for ITD: switch(config)# feature itd switch(config)# itd device-group dg switch(config-device-group)# switch(config-device-group)# switch(config-device-group)# weight 2 switch(config-device-group)# mode hot standby switch(config-device-group)# standby Related Commands Command feature itd itd device-group v6 Description Enables the ITD service on the switch. Creates an ITD device group. Creates an IPv6 cluster node for ITD. 3
4 v6 v6 To create an IPv6 cluster node for Intelligent Traffic Director (ITD), use the v6 command. To remove the cluster node, use the no form of this command. v6 ipv6-address [mode hot-standby] [standby ipv6-address] [weight value] no v6 ipv6-address [mode hot-standby] [standby ipv6-address] [weight value] Syntax Description ipv6-address mode hot-standby standbyipv6-address weight value IPv6 address for the node in the format A:B::C:D. (Optional) Specifies that the node is a standby node. (Optional) Specifies that the node is a standby for the active node. (Optional) Specifies proportionate weight for the node for weighted traffic distribution. Command Default None. Command Modes Device group configuration (config-device-group) network-adminvdc-admin Command History Release 6.2(10) 6.2(8) Modification The following keywords and arguments were added: standby ipv6-address and weight value. This command was introduced. Usage Guidelines You must ensure that ITD is enabled before you enter this command. You can enter the feature itd global configuration mode command to enable ITD. The v6 ipv6-address mode hot-standby command allows you to specify that a particular node is the standby node if a failure occurs. ITD redirects traffic away from the failed node to the newly active (standby) node. When the failed node becomes operational again, it is reinstated as an active node and traffic from the standby node is redirected back to the original node. The standby node reenters the pool of standby nodes. The v6 ipv6-address standby ipv6-address command allows you to specify that a particular node is the standby node for the active node with which it is associated. 4
5 v6 An ITD device group can have either IPv4 or IPv6 nodes, but not both. Before modifying the service parameters or device-group parameters, you must enter the shutdown command. Once the required parameters are modified, you should enter the no shutdown command on the service. This command requires the Enhanced Layer 2 Package license. Examples This example shows how to configure IPv6 nodes for ITD: switch(config)# feature itd switch(config)# itd device-group dg switch(config-device-group)# v6 ffff:eeee::dddd:eeee fefe:efef::dcdc:cccc This example shows how to configure weighted load balancing on the IPv6 nodes for ITD: switch(config)# feature itd switch(config)# itd device-group dg-v6 switch(config-device-group)# v6 ffff:eeee::dddd:eeee fefe:efef::dcdc:cccc weight 2 Related Commands Command feature itd itd device-group Description Enables the ITD service on the switch. Creates an ITD device group. Creates an IPv4 cluster node for ITD. 5
