Version 3.3.4.1

Example:

interface vlan 2

ip vrrp 2 ip 192.168.0.254
ip vrrp 2 priority 250
ip vrrp 2 timers advertise 180

console#show ip vrrp interface vlan 2 2

Primary IP Address............................. 192.168.0.254

62xx switches do not have the option to accept ping packets on vrrp virtual interface. Some other powerconnect switches do have this function that was introduced in firmware updates.

Are you wanting the 2 switches to back each other up? What is the overview of how you are wanting the VRRP set up?

Can you run these commands and provide the output on both switches?

console# show ip vrrp interface brief

console# show ip vrrp interface stats vlan #

console# show ip vrrp brief

console# show ip vrrp

Do you have the clients pointed to the IP 192.168.0.254 for their gateway? This is what would give the redundancy if the switch went down.

Hope this helps,

Keep us updated if you can.

I want to configure VRRP on two switches to failover in hot standby. Same as Cisco's HSRP, where a Virtual IP responds by VRRP

 asset which would be the network gateway.

I do not have this command: show ip vrrp brief

console#show ip vrrp interface brief

Look's like everything is set up properly. What you have is a Master/Backup that is similar to the Cisco HSRP Active/Standby. The main difference is that VRRP is limited to 2 devices where Cisco has the option to set up a group of devices for further redundancy. The third... device is listening and can take over as backup if a failover occurs.

In both cases the Master/Active is handling the gateway and sending information to the Backup/Standby for failover redundancy.

Hello ! I'm searching for VRRP capabilities of 6248. I have two PC6248 both running 3.3.2.3 firmware and I'm intend to set vrrp between then to achieve some redundancy. Reading the above conversations it seems there are some limitations of icmp reply responses from virtual ip address used in vrrp configuration. is this limitation corrected on newer firmware versions ?  Thanks in advance  and sorry for my poor english !!

The option to ping virtual ip address of the VRRP router was added in the 4.x firmware. The 62xx model is locked at level 3.x firmware.

It does not look like the feature is going to be added to the 62xx model in the near future, if at all.
