Group Priority
Whenever more than one switch is able to take over from a failed switch, the one with
the highest priority will be chosen. Possible values are 0–255, the default is 100.

Hold Time
If no hello packets are received from a switch for this group within the interval
specified here, the switch will be declared failed. Possible values are 100–600,000

Traced Port
Identification of the (virtual ATM) port connected to the emulated (or other legacy)
Token-Ring. When you select this item, you will be prompted for a box (stack only)
and port number. If the value(s) entered identifies an ATM Trunk Port, a list of
CRFs configured on this port are displayed. Select one. See Figure 27 on page 142.

Backup for Primary Port
Identifies a port for forwarding traffic that has been taken over from a failed switch.
This port must be connected to the same legacy Token Ring as the port that
identifies (together with Group Id) the DSRR group that is being configured. See
Figure 27. on page 142.

Backup for Traced Port
Identifies a backup port for forwarding traffic that has been taken over from a failed
switch. If the Traced Port is a Virtual ATM Port, the backup port must be able to
join the same emulated Token-Ring as the Traced Port. Otherwise it must be
connected to the same ring as the Traced Port. See Figure 27. on page 142.
