hello

when using snmpwalk on 2960 to get cdp neighbours information, I get the output like this:

C:\usr\bin>snmpwalk -v 2c -c R0b0ts21 10.242.48.13 .1.3.6.1.4.1.9.9.23.1.2.1.1.4

SNMPv2-SMI::enterprises.9.9.23.1.2.1.1.6.10112.11 = STRING: "6509-core2"

C:\usr\bin>

with a strange string

SNMPv2-SMI::enterprises.9.9.23.1.2.1.1.4.10102.15 = STRING: "

т0      " instead of ip address.

And it works absolutely correct with several other switches with same images

What could be the source of the problem?

Hi, 

What is the result when you walk cdpCacheAddressType?

SNMPv2-SMI::enterprises.9.9.23.1.2.1.1.4.10102.15

cdpCacheAddress

DESCRIPTION    "The (first) network-layer address of the device's SNMP-agent as reported in the most recent CDP message. For example, if the the corresponding instance of cacheAddressType had the value 'ip(1)', then this object would be an IP-address."

cdpCacheAddressType

DESCRIPTION    "An indication of the type of address contained in the corresponding instance of cdpCacheAddress."

SYNTAX        Integer { ip(1), decnet(2), pup(3), chaos(4), xns(5), x121(6), appletalk(7), clns(8), lat(9), vines(10), cons(11), apollo(12), stun(13), novell(14), qllc(15), snapshot(16), atmIlmi(17), bstun(18), x25pvc(19), ipv6(20), cdm(21), nbf(22), bpxIgx(23), clnsPfx(24), http(25), unknown(65535)}

thanks i solved this problem by loading mib file to my net-snmp

C:\usr\bin>snmpwalk  -m CISCO-CDP-MIB -c R0b0ts21 -v 2c 10.242.48.13 .1.3.6.1.4.

1.9.9.23.1.2.1.1.4

CISCO-CDP-MIB::cdpCacheAddress.10101.1 = STRING: a:f2:30:e

CISCO-CDP-MIB::cdpCacheAddress.10102.15 = STRING: a:f2:30:9

CISCO-CDP-MIB::cdpCacheAddress.10103.16 = STRING: a:f2:30:10

CISCO-CDP-MIB::cdpCacheAddress.10104.3 = STRING: a:f2:30:11

CISCO-CDP-MIB::cdpCacheAddress.10105.21 = STRING: a:f2:30:12
