Hi,
We r running the 2.6 version of CW and trying to figure out how to do SNMP walk to a device that we can successfully ping from CW...Can anybody please help us?
thanks.

You can do SNMP Walks from the Device Center. Just click on the Device Center link on the CiscoWorks Homepage, select a device (really any device will do), then select the SNMP Walk tool in the bottom left-hand pane.

Thanks fo your response, but I do not have the SNMP walk as a choice. Here are my choices:
Tools
Management Station to Device
Ping
Telnet
Trace Route
Edit Device Credentials
Cluster Management Suite
Cisco View
Mini RMON
thanks again...

You may not have access to the snmp walk due to your login access. Please ensure you are login in as an admin however your log in access is set up. Hope this helps.

If I do the Cisco View on a specific device, would it be comparable to doing SNMP walk?
thanks...

Not at all. While CiscoView will do SNMP queries on the device, it does not do one large sequence of SNMP GETNEXT requests to get all or large chunks of the MIB tree. Instead it will do pointed SNMP GET and GETNEXT requests to get enough information to generate the CiscoView image of the device.

Hi,
I have tried myself the SNMP Walk tool several times to retrieve the mac addresses stored in the MIBs because we suffer User Tracking discovery problems in some of out switches. However the query doesn't display the mac addresses in a readable format. I paste hereafter an example. Justs dots instead of the Hex addresses. Has somebody else experience this behaviour?
.1.3.6.1.2.1.17.4.3.1.1.0.3.136.6.16.50 = STRING: ".....F"
.1.3.6.1.2.1.17.4.3.1.1.0.3.144.23.131.98 = STRING: "......"
.1.3.6.1.2.1.17.4.3.1.1.0.12.36.78.26.104 = STRING: "..0b ."
.1.3.6.1.2.1.17.4.3.1.1.0.12.122.115.114.101 = STRING: "....z."
.1.3.6.1.2.1.17.4.3.1.1.0.21.232.134.13.109 = STRING: "...~.f"

This bug was fixed in LMS 2.6. However, the numeric values on the left-hand side of the equal sign are the MAC address in decimal notation. For example, the first MAC is:
0.3.136.6.16.50 or 00:03:88:06:10:32

That's a useful hint. Since the snmpwalk tool doesn't specify any vlan, I guess all the systems mac retrieved belong to the default vlan 1 or otherwise the tool queries for every vlan in the switch? According to my output, it's rather the first. How can I be sure that I'm retrieving the macs corresponding to all the vlans in my switch?
Thanks

With SNMPv1/v2c, you have to use community string indexing to get MACs from all VLANs. See http://www.cisco.com/en/US/tech/tk648/tk362/technologies_tech_note09186a00801c9199.shtml and ftp://ftp.cisco.com/pub/mibs/supportlists/wsc6509/wsc6509-communityIndexing.html for more information.
