Configure Segment
ID
Configure a local segment ID for a token ring ELAN in the LECS database.
Specify the ELAN name.
Each token ring segment in a token ring network that uses source routing
must be assigned a unique segment ID by the network administrator. You
assign the segment ID to the ATM ELAN, which simulates the token ring,
by this command. Then, when a LEC joins the ELAN, it gets the segment
ID from the LECS. Alternatively, instead of using this command, you can
configure the segment ID manually in each individual LEC in the ELAN.
You cannot assign a segment ID to a non-token ring ELAN.
