Is it common practice to disable CDP on access ports?
I am seeing CDP entries in Wireshark for the network I am connected to (Cisco_0a:ff:96 CDP/VTP/DTP/PAgP/UDLD). When I drill down into the packet, specifically under the "Cisco Discovery Protocol" field, I see that the Native VLAN is incorrect. The native VLAN for the subnet I am on, should be 50, but Wireshark shows the Native VLAN as 29, which is the subnet I am attached to.
The trunk port of the switch I am connected to has the "switchport trunk native vlan 50" command.
Giuseppe, the trunk port contains "trunk native vlan", the access port contains "access vlan". The trunk and access commands are not on the same port. In other words, the access port I am connected to (fa0/22) is not trunking.
