kamikatze posted : scli is pretty complex, but i can't confirm it can return the exact info `show dsl int` does.

#scli -c "show scli command tree" | grep -i atm   |- atm   |     |- info           show atm interface info    |     `- details        show atm interface details

What snmp client are you using to browse the tree?
If snmpwalk doesn't list the interface, you've probably hit a bug in IOS's snmpd.

You can always do a little Python magic to grab what you need from IOS CLI via ssh ;)

import pexpectimport os password = 'bobloblaw' ssh = pexpect.spawn("ssh user@router")ssh.expect('Password:')ssh.sendline(password) ssh.expect('IneedMoreRAM>')ssh.sendline('show ip bgp summary') ssh.expect('IneedMoreRAM>')print ssh.before ssh.sendline('exit')ssh.sendline('exit')ssh.close()

You get the idea..

code0 posted : Looks interesting, but it doesn't solve my problem. If I want to look at interface status, I can see it by looking at the ATM "interface" associated with the connection ("ATM0/0-atm layer" for example).

My need is to monitor the DSL related stats like below:

Multiple ADSL WIC SNMP weirdness

Wed, 08 Jul 2009 09:13:58 EDT

code0 posted : We've got a 3745 currently with 4 ADSL WICs (ATM0/0, ATM0/1, ATM0/2, and ATM1/0) - 2 are active at the moment.

The weirdness is that only the first WIC shows as a DSL interface to SNMP. Also, when I walk the DSL interface statistics tree, I only see stats for ATM0/0, and not 0/1 (I wouldn't expect the other 2 since they aren't live at the moment). I checked the configuration for the interfaces, and they are exactly the same. Have I hit some sort of limit?

BTW, the 2 live connections are part of a MLPPP link.

ADSL WIC config (all are the same):


interface ATM0/0
 no ip address
 no atm ilmi-keepalive
 dsl operating-mode auto 
 hold-queue 224 in
 pvc 0/32 
  encapsulation aal5mux ppp dialer
  dialer pool-member 1
