Configuring SmartTRUNKs
Add Physical Ports to the SmartTRUNK
You can add any number of ports to a SmartTRUNK. The limit is the number of ports on
the GSR. Any port on any module can be part of a SmartTRUNK. If one module should go
down, the remaining ports on other modules will remain operational.
Ports added to a SmartTRUNK must:
• Be set to full duplex.
• Be in the same VLAN.
• Have the same properties (L2 aging, STP state, and so on).
To add ports to a SmartTRUNK, enter the following command in Configure mode:
Specify Traffic Distribution Policy (Optional)
The default policy for distributing traffic across the ports in a SmartTRUNK is “round-
robin,” where the GSR selects the port on a rotating basis. The other policy that can be
chosen is “link-utilization,” where packets are sent to the least-used port in a
SmartTRUNK. You can choose to specify the link-utilization policy for a particular
SmartTRUNK, a list of SmartTRUNKs, or for all SmartTRUNKs on the GSR.
Create a SmartTRUNK that will be connected
to a device that supports the DEC Hunt Group
Control Protocol.
