[GoogleNet-S5720] monitor-link group 1
[GoogleNet-S5720-mtlk-group1] port XGigabitEthernet0/0/1 uplink
[GoogleNet-S5720-mtlk-group1] port GigabitEthernet0/0/1 downlink 1
[GoogleNet-S5720-mtlk-group1] port GigabitEthernet0/0/2 downlink 2
[Net4planet-S5720]
[Net4planet -S5720] monitor-link group 1
[Net4planet -S5720-mtlk-group1] port XGigabitEthernet0/0/1 uplink
[Net4planet -S5720-mtlk-group1] port GigabitEthernet0/0/1 downlink 1
[Net4planet -S5720-mtlk-group1] port GigabitEthernet0/0/2 downlink 2
