Usage

Active forwarding cannot be configured when ICMP redirect is enabled. Enter the no ip icmp redirect command for disabling ICMP redirect.

IMPORTANT:

Active forwarding cannot be configured when ICMP redirect is enabled. The ICMP redirect setting is global not per SVI.

If a system has active forwarding enabled, an active gateway can have a maximum of 14 "unique" MAC addresses per system, including IPv4 and IPv6 addresses.

If a system has active forwarding disabled, an active gateway can have a maximum of 16 "unique" MAC addresses per system, including IPv4 and IPv6 addresses.

Examples

Attempting to enable VSX active-forwarding on an interface that has an active-gateway enabled:

switch# interface vlan 3
switch(config-if-vlan)# vsx active-forwarding
Active-forwarding cannot be enabled on an interface that has active-gateway enabled

Successfully enabling VSX active-forwarding:

switch# interface vlan 3
switch(config-if-vlan)# vsx active-forwarding
switch(config-vsx)#

Unconfiguring VSX active-forwarding:

switch# interface vlan 3
switch(config-if-vlan)# no vsx active-forwarding
switch(config-vsx)#
