Table 5-2 Trunk hashing configuration commands
In Example 5-19, source MAC address hashing was enabled for all switches and for
RackSwitch G8264, and ingress port hashing was also configured.
Example 5-19 Configure trunk hashing
AGG-1#configure terminal
Enter configuration commands, one per line. End with Ctrl/Z.

Syntax: There are command syntax differences between the RackSwitch G8264
and RackSwitch G8124 switches. Both sets of commands are presented in
Table 5-2 on page 173.
