Hi


We are trying to extend our server farm infastructure with Cisco 6509e's running IOS. Current server farm switches are 6509's with CatOS.


The switches are all connected together, with all the VLANs being trunked. Currently the catOS switches are the STP root bridges and active layer 3 interfaces for all the VLANs.

We can make the new switches the STP root bridges no problems. But when we try to make the layer interface by increasing the HSRP priority we get Duplicate IP address messages coming up.


Any help would be great!

Could you please post the configurations of the layer-3 interfaces on both switches. One VLAN will do, just to get the picture of how you have the HSRP configured.

Hi


VLAN Interace config is as (minus IP addresses):


SW1 (MSFC1):


interface VlanX

bandwidth 1000000

ip address x.x.x.x.1 255.255.255.0

ip helper-address x.x.x.x

no ip redirects

ip pim sparse-dense-mode

ip route-cache flow

ipx network XXXXXX encapsulation SAP

standby 1 ip x.x.x.3

standby 1 priority 100

standby 1 preempt

standby 1 track VlanXXX 20


SW2 (MSFC1) :


interface VlanX

bandwidth 1000000

ip address x.x.x.x.2 255.255.255.0

ip helper-address x.x.x.x

no ip redirects

ip pim sparse-dense-mode

ip route-cache flow

ipx network XXXXXX encapsulation SAP

standby 1 ip x.x.x.3

standby 1 priority 90

standby 1 preempt

standby 1 track VlanXXX 20


The configs are very similar between the switches, only difference is the IP address and standby priorities.

Where are the messages coming up?

Are you using HPOV?

Hi Anawaz


I am carrying out more testing this w/e, by creating a new test VLAN, i will try to apply an access list in the VLAN interfaces.
