Chapter 6 Configuring EtherChannel
Configuring an EtherChannel Using PAgP
PAgP Administrative Groups
Configuring an EtherChannel creates an administrative group, which is designated by an integer between
1 and 1024, to which the EtherChannel belongs. When an administrative group is created, you can assign
an administrative group number or let the next available administrative group number be assigned
automatically. Forming a channel without specifying an administrative group number creates a new
automatically numbered administrative group. An administrative group may contain a maximum of eight
ports.
Enter the
show channel group
command to verify that all ports in an EtherChannel belong to the same
administrative group, and enter the
set port channel
mod/ports
admin_group
command if necessary to
assign ports to the same administrative group.
PAgP EtherChannel IDs
Each EtherChannel is automatically assigned a unique EtherChannel ID. Enter the
show channel group
admin_group
command to display the EtherChannel ID.
