Chapter7 Configuring APS
Configuring APS Group Attributes
Note Both nodes in the network that add and drop the channel must h ave the same A PS configurat ion.
Specifically, both must have the same path switching behavior, and working and protection paths.
Note For interfaces with either Sysplex ETR or Sysplex CLO protocol encapsulation, configure
bidirectional path switching to ensure proper functioning of the protocol.
Examples
Figure 7-10 shows the active and standby paths between node 1 and node 2 with splitter protection.
Figure7-10 Bidirectional Path Switching Example with Splitter Protection
The following example shows how to configure one channel in the example netwo rk for b i dire cti on al
path switching using the default working and protection path interfaces:
Node1# configure terminal
Node1(config)# redundancy
Node1(config-red)# associate group red
Node1(config-red-aps)# aps working wavepatch 4/0/0
Node1(config-red-aps)# aps protection wavepatch 4/0/1
Node1(config-red-aps)# aps direction bidirectional
Node1(config-red-aps)# aps enable
Node2# configure terminal
Step6 Switch(config-red-aps)# aps timer message
max-interval seconds Changes the APS Channel Protocol maximum interval
timer for waiting for a message. The default is
15 seconds. (Optional)
Repeat Step 1 through Step 6 on the corresponding
transparent interface on the other node that adds and
drops, or terminates, the channel.
Step7 Switch(config-red-aps)# aps message-channel
{auto-select [far-end group-name name] |
inband dcc [far-end group-name name] |
ip far-end group-name name ip-address
ip-address | osc [far-end group-name name]}
Configures the message channel for the APS channel
protocol messages. The default is auto-select without
a group name. (Optional)
Step8 Switch(config-red-aps)# aps enable Enables APS activity between the interfaces.
