Layer 2 and Layer 3 LAN connections
To troubleshoot for Layer 2 and Layer 3 LAN connection, follow the steps in
Procedure 7.
Procedure 7
Troubleshooting Layer 2 and Layer 3 LAN connections for MG 1000T
1 Verify that the green Link LED on the daughterboard in the MG 1000T
Core SSC is on (this indicates that the physical connection is functioning).
If the Link LED is off, check the physical connection by verifying that the
daughterboard and cables are properly installed.
2 Test the LAN connectivity between the MG 1000T Core and the
Layer 2/3 switch by pinging the IP address of the Layer 2/3 switch.
Perform the same test between the MG 1000T Expansion and the Layer
2/3 switch. Consult the local IS department for the appropriate IP address.
3 To disable the link for testing, in LD 32, enter DISS <n> (where n = IP
daughterboard port#).
4 To test the signaling and voice path of the daughterboard, in LD 135,
enter LLBK <link #> . If the card fails the LLBK test, replace the IP
daughterboard.
5 Verify that the MAC address of the MG 1000T Expansion is correctly
configured on the MG 1000T Core. In LD 117, enter PRT IPR to access
the MAC data.
6 In LD 117, enter PING <ip address of the MG 1000T Expansion> to
verify the network connection.
7 Re-enable any disabled components. Verify that the 100BaseT
connection between the MG 1000T Core and the MG 1000T Expansion
is operating by pinging the IP address of the MG 1000T Expansion(s)
configured.
Note: The MG 1000T platform supports only Layer 2 and Layer 3
switches. Software routers are not recommended.
