L2 Port Bridge
The L2 port bridge feature allows the port to forward the packets that the outgoing inter-
face in the MAC address entry is the same as the incoming interface where the packet ar-
rived. If one port is enabled with L2 port bridge feature, it forwards the packets to its des-
tination port when the MAC address is found in the L2 table. The switch can have multiple
MAC addresses associated with the same port.
To enable/disable the L2 port bridge feature, use the following command.
Command
Mode
Description
switchport port-bridge
Interface
[XE/GE]
Enables L2 port bridge feature on the interface.
no switchport port-bridge
Disables L2 port bridge feature. (default)

Port Crossover
MDI/MDIX is a type of Ethernet port connection according to the IEEE 802.3 standard us-
ing twisted pair cabling. Uplink ports on hubs and switches use the same pin assignments
that use pins 1 and 2 for transmit and 3 and 6 for receive. These ports are called Medium
Dependent Interface (MDI) ports. Normal ports use the opposite pin assignment, i.e. pins
1 and 2 are used for receive and pins 3 ans 6 are used for transmit. Such ports are called
MDIX (MDI-crossed) ports.
