To establish a session on a port-channel:
Step Task
1 Establish a session on a port-channel.
View the established sessions using the command
Figure 9-28. Viewing Established Sessions for VLAN Neighbors

Changing port-channel session parameters
BFD sessions are configured with default intervals and a default role. The parameters that can be
configured are: Desired TX Interval, Required Min RX Interval, Detection Multiplier, and system role.
These parameters are configured per interface; if you change a parameter, the change affects all sessions on
that interface.
Caution: When configuring BFD on VLAN or LAG interfaces on the C-Series, Dell Force10 recommends
a minimum value of 500 milliseconds for both the transmit and minimum receive time, which yields a final
detection time of (500ms *3) 1500 milliseconds.
To change session parameters on an interface:
Step Task
1 Change session parameters for all
sessions on a port-channel interface.
View session parameters using the command
page 179.
Disabling BFD for port-channels
If BFD is disabled on an interface, sessions on the interface are torn down. A final Admin Down control
packet is sent to all neighbors, and sessions on the remote system are placed in a Down state
