Adding A Port To An Aps Group - Extreme Networks PoS Installation And User Manual

Configuring the PoS Module

Adding a Port to an APS Group

To add a SONET port to an APS group, use the following command:
config aps <group#> add <port> [working | protection <ipaddress>]
The parameter is an integer in the range from 1 to 65535 that identifies the APS
group#
group to which the specified port is to be added.
The parameter identifies the SONET port that is to be added to the APS group.
port
You must also specify whether the port is the APS working or protection line. You can
add only one working line and one protection line to an APS group. If you designate
the port the protection line, then you must also specify the IP address (
parameter) of the BlackDiamond switch where the working line resides. This IP address
is used to send APS control messages to the BlackDiamond switch containing the
working line.
The configured IP address should be associated with an Ethernet VLAN that has
loopback mode enabled to minimize the impact of network outages on APS
functionality. Also, when using APS to protect links on different BlackDiamond
6800 series switches, the network connecting the working and protection
switches must always have sufficient bandwidth to support APS control transfers.
In routing configurations, the working line and the protection line should represent the
same IP address from the perspective of the neighboring PPP switch. When the working
line and protection line reside in the same BlackDiamond switch, both ports should be
members of the same VLAN. The case where both the working line and the protection
line for an APS group reside in the same BlackDiamond switch is the only situation
where IPCP can be enabled on multiple SONET ports that are members of the same
VLAN. In general, if IPCP is enabled on a PoS module port, that port can be a member
of only one VLAN and no other ports on that switch can be members of that VLAN.
The following command example adds port 1 of the module installed in slot 8 of the
BlackDiamond switch to APS group 1001 as the working line.
config aps 1001 add 8:1 working
