Verifying The Wan Configuration And Testing Connectivity - Avaya G250 Administration

Verifying the WAN configuration and testing connectivity

After configuring the new interface, you can perform the following tests to verify that the new
interface is operating correctly.
For E1/T1 interfaces, use the show controllers command to view the status of the
●
interface's controller. Make sure the controller is up, and that all error counters do not
increase.
For all serial interfaces (E1/T1 and USB), use the show interfaces Serial command
●
to verify that the interface and line protocol are both up:
Serial x/y:z is up, line protocol is up
For USB interfaces only, use the show interfaces Serial command to verify that all
●
line signals are up:
DCD = up DSR = up DTR = up RTS = up CTS - up
Use the show frame-relay pvc command to view basic information about frame relay
●
configuration. For more information about frame relay configuration, use the following
commands:
- show frame-relay fragment to display frame relay fragmentation statistics and
configuration on all PVCs associated with the interface.
- show frame-relay lmi to display LMI statistics for the interface.
- show frame-relay map to display a summary table of frame relay sub-interfaces and
DLCIs associated with the sub-interfaces.
- show frame-relay traffic to display frame relay protocol statistics, including ARP
requests and replies sent and received over the interface.
- show map-class frame-relay to display the map-class Frame Relay table.
Use the show ip interface command to display information about IP interfaces. To
●
display information about a specific interface, include the name of the interface as an
argument. To display information about the interface of a specific IP address, include the
IP address as an argument.
Use the show running-config command to display the configuration running on the
●
device.
Use the show startup-config command to display the configuration loaded at startup.
●
Use the
ping command to send ICMP echo request packets from the G250/G350 to the
●
interface serial peer IP address and verify that it responds.
Use the ping command to send ICMP echo request packets to another node on the
●
network. Each node is periodically pinged and checked if an answer was received. This
checks host reachability and network connectivity.
