Use the following procedures and tips to resolve ThinkAgile SXM network issues that might arise.
RackSwitch G8052 (ENOS): show interface transceiver
All the other Lenovo switches: display
interface transceiver
Check the physical connection of the cable to the port. If necessary, reconnect the cable.
RackSwitch G8052 (ENOS): show interface transceiver
All other Lenovo switches (CNOS): display interface transceiver
Use interface port <port_number>
to enter interface configuration mode.
Use shutdown
to disable the port.
Use no shutdown
to enable the port.
Use interface eth 1/<port_number>
to enter interface configuration mode.
Use shutdown
to disable the port.
Use no shutdown
to enable the port.
RackSwitch G8052 (ENOS): show spanning-tree
All other Lenovo switches (CNOS): display spanning-tree
RackSwitch G8052 (ENOS): show running-config
All other Lenovo switches (CNOS): show spanning-tree mst interface ethernet 1/<port_number>
RackSwitch G8052 (ENOS): show vlan
All other Lenovo switches (CNOS): display vlan summary
Use the vlan <vlan_ID>
command to
enter VLAN configuration mode.
Use the shutdown
command to disable the VLAN.
Use the no shutdown
command to enable the
VLAN.
Use the interface <interface_name>
to enter the interface configuration mode.
RackSwitch G8052 (ENOS): switchport trunk allowed vlan <add/remove> <vlan_ids>
All other Lenovo switches (CNOS): bridge-port trunk allowed vlan <add/remove> <vlan_ids>
RackSwitch G8052 (ENOS): show interface ip
All other Lenovo switches (CNOS): display running-config ip
Use the display ip interface brief
command on the Lenovo switches running CNOS to verify whether the
link status is UP for all IP interfaces.
RackSwitch G8052 (ENOS): show interface ip
or show ip gateway 1
All other Lenovo switches (CNOS): display ip interface
or display run vrf management
Confirm whether the RackSwitch G8272 switches can ping the gateway: ping <G8052_management_port_IP> vrf management
RackSwitch G8052 (ENOS): show ip arp
All other Lenovo switches (CNOS): display ip arp vrf management
Check the management port state.
Ensure that the port channel is UP and active.
Ensure that the port channel type (static or dynamic) on both ends is identical.
Use the CNOS command display port-aggregation summary
to ensure that all port-channel are UP in port-aggregation.
Use the CNOS command display vlag information
to ensure that vLag ISL is enabled, UP, and active. Also, check
to see that the vLag peer-id on both RackSwitch G8272 switches are the same.
