Verifying and Troubleshooting Configured Interfaces

DETAILED STEPS
Command or Action
Step 1
show interfaces type instance
Example:
RP/0/RP0/CPU0:router# show interfaces
gigabitEthernet 0/0/0/0
Step 2
show controllers interface-type
interface-instance stats
Example:
RP/0/RP0/CPU0:router# show controllers
gigabitEthernet 0/0/0/0 stats
Step 3
show netio idb interface-type
interface-instance
Example:
RP/0/RP0/CPU0:router# show netio idb
gigabitEthernet 0/0/0/0
Step 4
show controllers plim asic statistics interface
type instance
or
show hw-module subslot address counters mac
index
or
show hw-module subslot counters framer
Example:
RP/0/RP0/CPU0:router# show controllers plim
asic statistics interface tenGigE 1/3/0/0
or
RP/0/RP0/CPU0:router# show hw-module subslot
0/0/0 counters mac 0
or
RP/0/RP0/CPU0:router# show hw-module subslot
counters framer
Step 5 Contact Cisco Technical Support.
The following example shows POS 0/0/1/0 with no input drop counters.
RP/0/RP0/CPU0:router# show interfaces pos 0/0/1/0
POS0/0/1/0 is up, line protocol is up
Hardware is Packet over SONET/SDH
Internet address is 172.18.140.1/24
MTU 4474 bytes, BW 155520 Kbit

Purpose
Displays statistics for all interfaces configured on the
specified node. Check for interface errors.
Displays interface controller status and configuration
statistics for the specified node. Check for input drops.
If input drops are found, contact Cisco Technical Support.

"Obtaining Documentation and Submitting a Service
Request" section on page viii
Displays network input and output information for a
specified node.
Check the software counters for the interface. Under Chains
and Protocol chains in the output check if any drops
occurred at a particular point in the Encap or Decap of the
packet. The drops are displayed in the column on the right,
showing drop packets and bytes for each step in the chain.
Use the show controllers plim command for fixed
•
PLIMs. Check for interface drops on fixed physical
layer interface modules (PLIMs).
Use the show hw-module subslot address counters
•
mac command and show hw-module subslot counters
framer command for shared port adapters (SPAs).
Check for interface drops on SPAs.
Check the application-specific integrated circuit (ASIC)
counters for drop counters or error counters incrementing
for the interface.
