Significance of the VLAN IP address
Posted on 2012-09-19
Hi, Please advise
We are having odd problems on 1 floor. We have VLANS for each floor - Cisco 2960's. We have Cisco 3750 Core Switch's. Setup by Cisco engineer. On that core are all the floor VLAN IP's.(data vlan) On the troubled floor - its (VLAN ID is 213(data vlan)) - This has the VLAN IP in the core as such 192.168.3.99.
The 1 difference with this floor (3) is that on the floor switch stack it (unlike the other floor stacks) has the VLAN IP listed as 192.168.3.98 for vlan 213. - so core .99 and floor stack .98 for the same vlan?
So I guess im asking - what is the significance of the VLAN IP - or is this just significant for management (eg to telnet to the VLAN) ? - The odd behavior on this floor - is ping timeouts - a voip phone not getting dhcp address (vlan issue) - some general network type issues. - So with this mismatch in IP VLAN for 213 - is this a possible cause - maybe just a typo by Cisco engineer. - None of the other switches on the other floors have 2 different vlan IP's
I'm waiting to hear back from engineer - just need clarification please
