The fields in xmapls table are defined as follows:
VPN. The local virtual port number which is connected to an adjacent switch.
Rem Switch ID. The MAC address of the MPX in the adjacent switch.
Rem VPN. The remote virtual port number in the adjacent switch.
Pri Group. The primary group associated with the remote port. The primary group is the group
upon which Spanning Tree converges. For more information about primary groups, see Chap-

IP Addresses. All IP addresses associated with the adjacent switch.

Configuring the Discovery Transmission Time

The discovery transmission time is used in both the discovery transmission state and the
common transmission state to determine how long the port will wait for Hello packets. For
ports in the discovery transmission state, this timer is also used as the interval between send-
ing out Hello packets.
♦ Note ♦
Ports in the common transmission state send out Hello
packets based on the common transmission time as
described in the next section.
Use the xmapdisctime command to view or update the discovery transmission time.
To view the current discovery transmission time, enter the following command:
