Switch-Based VRRP Group Commands
The following are procedures for server-based VRRP group commands.
To configure a switch-based VRRP group

For more information on using switch-based VRRP groups with hot standby, see
Configuration, page 537.
Tracking VRRP Router Parameters
Alteon supports a tracking function that dynamically modifies the priority of a VRRP router based on
its current state. The objective of tracking is to have, whenever possible, the master bidding
processes for various virtual routers in a LAN converge on the same Alteon. Tracking ensures that
the selected Alteon is the one that offers optimal network performance. For tracking to have any
effect on virtual router operation, preemption must be enabled.
Note: Tracking only affects hot standby and active-standby configurations. It does not have any
effect on active-active sharing configurations.
Alteon can track the parameters outlined in the following table:
Parameters and Commands
Number of virtual routers in master mode on
Alteon.
• To enable tracking on VRs:
/cfg/l3/vrrp/vr<#>/track/vrs/ena
• To change the virtual router increment:
/cfg/l3/vrrp/track/vrs <[0-254]>
Number of IP interfaces active on Alteon.
• To enable tracking on IP interfaces:
l3/vrrp/vr/track/ifs <#> /ena
• To change the interfaces tracking
increment:
/cfg/l3/vrrp/track/ifs <[0-254]>
Number of active ports on the same VLAN.
• To enable tracking on ports on the same
VLAN:
/cfg/l3/vrrp/vr/track/port<#>/ena
• To change the ports tracking increment:
/cfg/l3/vrrp/track/ports <[0-
254]>

Table 48: VRRP Tracking Parameters
Description
Useful for ensuring that traffic for any particular
client/server pair is handled by the same Alteon,
increasing routing and load balancing efficiency.
This parameter influences the VRRP router's
priority in both virtual interface routers and
virtual server routers.
Note:
tracking for a service-based virtual router
group (vrgroup).
Helps elect the virtual routers with the most
available routes as the master. An IP interface is
/cfg/
considered active when there is at least one
active port on the same VLAN. This parameter
influences the VRRP router's priority in both
virtual interface routers and virtual server
routers.
Helps elect the virtual routers with the most
available ports as the master. This parameter
influences the VRRP router's priority in both
virtual interface routers and virtual server
routers.
The vrs parameter is not available for
