To view FDB entries, use the following
command:
show fdb netlogin [all | mac-based-vlans]
By specifying netlogin, you see only FDB entries related to network
login or network login MAC-based VLANs.
The flags associated with network login include:
- v—Indicates the FDB entry was added because the port is part of a MAC-Based virtual
port/VLAN combination
- n—Indicates the FDB entry was added by network login
