Our current network is comprised of about 50 Cisco switches, all C2950s or C2960s, with a C6500 and C3750 stack at the core.
Because our network had components from another vendor, the previous network administrator decided to use VLAN 1 as the management VLAN. The IT supervisor here made mention of changing all the switches over to a different VLAN for security reasons. Is there an "easy way" to do this, or am I looking at creating a new VLAN and interafce at the core and then connecting to each individual switch in order to create their vlan interfaces and activate them, sweating the whole time because I just lost connectivity?
I don't also suppose there's any way to do this while not changing the subnets and IP addresses? (otherwise I'd be looking at redoing all of my documentation and automated backup/monitoring services)
I make sure that no ports on the switches are configured for VLAN 1 (typically 1 VLAN/subnet per switch/area and unused ports go to a dummy VLAN), so in reality, it only exists on the trunks which, being fiber optic, are a bit hard to splice into with no-one noticing. Is it something I should really be concerned about?
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
