MAC Based Trunking
MAC Based Trunking provides performance and provides media redundancy. See an example below for
multiple 508/509 Trunking configuration.
Command Description Comment

disable (or
enable) Enables Disables Trunking Choice is opposite
of current state
config Configure Trunking Group1 and/or/nor 2
Notes on Trunking:
• Mirroring overrides trunking (does mirror on the other trunk line). Can be used together carefully.
• Functionality, when trunking is enabled, on the 500 series is:
• If Trunk Groups 1 & 2 are both Activated:
o Ports 1 & 2 are a pair of forwarding ports.
o Ports 7 & 8 are a pair of forwarding ports.
* Each pair dynamically balances traffic and dynamically fails over.
* If port 1 goes down, ports 1/2 traffic is remapped to port 2 only.
* If port 2 goes down, ports 1/2 traffic is remapped to port 1 only.
* If port 7 goes down, ports 7/8 traffic is remapped to port 8 only.
* If port 8 goes down, ports 7/8 traffic is remapped to port 7 only.
* If both trunk ports of a pair are available, trunking is restored
to normal.
• If Trunk Group1 is Activated and Trunk Group2 is Deactivated:
o Ports 1 & 2 are a pair of forwarding ports.
* The pair dynamically balances traffic and dynamically fails over.
* If port 1 goes down, ports 1/2 traffic is remapped to port 2 only.
* If port 2 goes down, ports 1/2 traffic is remapped to port 1 only.
* If both trunk ports are available, trunking is restored to normal.
• If Trunk Group1 is Deactivated and Trunk Group2 is Activated:
o Ports 7 & 8 are a pair of forwarding ports
(functioning as above).
