ExtremeWare 7.7 Command Reference Guide 2281
configure aps add
configure aps <group#> add <port> [working | protection <ip address>]
Description
Adds a SONET port to an APS group.
Syntax Description
Default
By default, no ports are added to an APS group. Ports must be explicitly added using this command for
proper APS operation.
Usage Guidelines
You specify the
group#
parameter, which is an integer in the range [1-65535]. The
group#
identifies the
APS group that the port is to be added to. You also specify the
port
parameter, which identifies the
SONET port that is to be added to the APS group. Additionally, you specify whether the port is
designated as the working or protection line. Only one working line and one protection line can be
added to an APS group. If the port is designated as the protection line, then you must also specify an IP
address (
ip address
) 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. It is
recommended that the configured
ip address
be associated with an Ethernet VLAN that has loopback
mode enabled (to minimize the impact of network outages on APS functionality). It is important that
the network connecting working and protection switches always has sufficient bandwidth to support
APS control transfers.
In routing configurations, the working line and the protection line should represent the same IP address
from a neighboring PPP router's perspective. When the working line and protection line reside in the
same BlackDiamond switch, this implies that 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 the PPP IP control protocol (IPCP) can be enabled on
multiple SONET ports that are members of the same VLAN. In general, if IPCP is enabled on a SONET,
then the port can only be a member of one VLAN, and no others ports can be members of that VLAN.
Example
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
group# Specifies the APS
group#
to which the command applies.
port Specifies the SONET port number to be added to the APS group.
working Specifies that the port is the working line.
protection Specifies that the port is the protection line.
ip address Specifies the IP address of the BlackDiamond switch where working line
resides.
