ACIP Error Statistics
ACIP Error Statistics
The ACIPmaintains a count of certain errors. In addition to keeping a count of these errors, the ACIP
also takes a snapshot of the last VCI/VPI that caused the error. Each ACIP error counter is 16 bits.
Errors include the following:
• CRC errors
• Giants received
• No buffers available
• Framing errors
• Applique/physical layer errors
• Packet timeout errors on receive
Checking the Configuration
After configuring the new interface, use the show commands to display the status of the new
interface or all interfaces.
ATM show Commands
In addition to the show commands described in the section “Using show Commands to Verify
Interface Status,” on page 19, you can use the following additional show commands to display the
current state of the ATM network and the connected VCs:
• To show current VCs and traffic information, use the show atm vc [vcd] command:
Specifying a VCD will display specific information about that VCD.
• To show current ATM-specific information about an interface, use the show atm int interface
command:
• To show current ATM traffic, use the show atm traffic command:
This command displays global traffic information to and from all ATM networks connected to
the router.
Following are descriptions and examples of the preceding show commands:
• Use the show atm vc command to display the following types of statistics for all VCs:
