Hello, how I can verify whether an ATM PVC on an LS1010 "dropped cells". I can do on the controller, but I did not found any possibility to verify it per PVC.
Te command "sh atm vc int atm x/y/z [vpi] [vci] " show me the Tx an Rx Cells, but no dropped cells.
Thanks

Try the 'show atm vc detail' command.

Hi gmarogi,
thanks for the response, but the "column" detail" is not possible on a LS1010:
LS1010#sh atm vc interface atm 0/0/3 0 99 ?
LS1010#sh atm vc ?
cast-type VC Cast Type
conn-type VC Connection Type
interface Show ATM Connection Commands
signalling Display ATM Interface Signalling information for all interfaces
traffic Display Virtual Channels Cell Traffic

First, If you do not have the 'detail' option, then you most likely have an old code release.
Your ideal output should look like this:
1010#show atm vc int atm 4/0/0.1 2 100
[snip]
Threshold Group: 1, Cells queued: 0
Rx cells: 3735, Tx cells: 121573
Tx Clp0:121573, Tx Clp1: 0
Rx Clp0:3735, Rx Clp1: 0
Rx Upc Violations:2735, Rx cell drops:10
Rx pkts:130, Rx pkt drops:5
Since you have an old code release, the best output you are going to get is something like this. I grabbed this from an old 11.2 LS1010. No luck on the dropped cells/packets:
sh atm vc int atm3/1/2 250 250
Interface: ATM3/1/2, Type: oc3suni
VPI = 250 VCI = 250
Status: UP

Cross-connect-VCI = 250
Cross-connect-UPC: pass
Cross-connect OAM-configuration: disabled
Cross-connect OAM-state: Not-applicable
Rx cells: 3943223209, Tx cells: 3880783742

Second, I suggest you start reading Understanding Rejected/Discarded Cell Counters:
http://www.cisco.com/warp/public/121/rejectedcells.html
Third, The most you're going to get from SNMP is this:
The CISCO-ATM-CONN-MIB provides management information base (MIB) objects to gather per-VC statistics related to cell drops and discarded cells. Some of these objects were described in detail in previous sections.
CiscoAtmVclEntry
ciscoAtmVclRxUpcMode
ciscoAtmVclEpdEnable
ciscoAtmVclUpcViolations
ciscoAtmVclEpdTpdCellDrops
ciscoAtmVclEpdTpdPacketDrops
ciscoAtmVclEpdTpdPacketsIn
ciscoAtmVclLsPerVcQThreshGrp
ciscoAtmVclClp0VcqFullCellDrops
ciscoAtmVclVcqClpThreshCellDrops
You can get the MIB here->ftp://ftp.cisco.com/pub/mibs/v1/CISCO-ATM-CONN-MIB-V1SMI.my
You can use SNMP tools to find out your rejected and discarded cells. Specifically, you can use something like Cricket to view the reports of drops via the web such as here->http://www.frgp.net/~cricket/grapher.cgi?target=%2Frouter-stats%2Ffrgp-as-1&ranges=d%3Aw%3Am%3Ay&view=celldiscards
Fourth, your key phrases to search on Google are 'cell drops' and 'discarded cells'
I would seriously consider upgrading your code release so at least you can have show commands that give you the output you desire, as well as download some MIBS for SNMP.
