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 traffic-shape command to view traffic shaping and frame relay traffic
●
shaping configuration parameters for all interfaces.
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.
