Nortel Secure Router 8000 Series
Configuration -WAN Access
4-28 Nortel Networks Inc. Issue 5.3 (
30 March 2009)
# Configure POS 1/0/0. The clock mode is slave.
<RouterA> system-view
[RouterA] interface pos 1/0/0
[RouterA-Pos1/0/0] ip address 10.110.1.10 255.255.255.0
Step 2 Configure Router B.
# Configure POS 4/0/0, set clock mode the master modeas slave while all other physical
parameters use default values.
<RouterB> system-view
[RouterB] interface pos 4/0/0
[RouterB-Pos4/0/0] clock master
[RouterB-Pos4/0/0] ip address 10.110.1.11 255.255.255.0
Step 3 Check the configuration.
Use the display interface pos command to check the connectivity of POS interfaces on
Router A.
