b.
If the DR member devices use different DR system MAC addresses, use the
drni
system-mac
command to change the DR system MAC addresses of the DR member
devices to the same value.
3.
Verify that the DR member devices use the same DR system priority:
a.
Execute the
display drni system
command to identify the DR system priorities of the
DR member devices.
b.
If the DR member devices use different DR system priorities, use the
drni
system-priority
command to change the DR system priorities of the DR member
devices to the same value.
4.
Verify that an aggregate interface has been configured as the IPP:
a.
Execute the
display drni verbose
command to identify IPP information.
b.
If an IPP is not configured, use the
intra-portal-port
command to configure an
available aggregate interface as the IPP.
5.
Verify that the IPP is up:
a.
Execute the
display interface
command to examine the state of the interface that acts
as the IPP.
b.
If the IPP is in
DOWN (Administratively)
state, use the
undo shutdown
command to bring
it up. If the IPP is in
DOWN
state, examine the member ports of the IPP and make sure the
following requirements are met:
−
Their optical fibers or copper cables are correctly installed.
−
Their transceiver modules are operating correctly.
NOTE:
The transceiver modules and optical fibers supported for IPL setup vary by software version
and hardware. To obtain DRNI hardware compatibility information, see the configuration
guides for the DR member devices.
