By default there are three types of traffic that pass through Catalyst switches:
Control traffic includes CDP, VTP ,PAgP
Management traffic includes end-to-end and IP-based protocols such as Telnet, SNMP, and VQP (the protocol used by VMPS). These protocols always use the VLAN assign to SC0.
by default all three traffics are assigned to VLAN 1. Can we change a management VLAN to any VLAN ?, if we change a management vlan to another VLAN will control traffic is also changed automatically to the new management vlan or not?
And if we change management vlan to another VLAN and if we assume that even control traffic is changed automatically to new management vlan, will this switch in which management vlan has changed to another VLAN will communicate with control traffic of another switch's control traffic that uses VLAN 1 as management vlan .
