Description Shinji Kito 2011-02-25 07:55:58 UTC 
Description of problem:
This is the same issue reported in BZ#627564, and
a customer would like to backport it to RHEL5.

When using IPV6-MIB to query the description of IPV6 interfaces, only
the interfaces up at the time of startup are reported, any
interfaces activated after startup are not reported.


Version-Release number of selected component (if applicable):
RHEL5.6
net-snmp-5.3.2.2-9.el5_5.1 

How reproducible:
Always

Steps to Reproduce:
1. Check the current interfaces
    # cat /proc/net/if_inet6 
    00000000000000000000000000000001 01 80 10 80       lo
    fe80000000000000505400fffe0fcad9 03 40 20 80     eth

2. Start snmpd
   # service snmpd start

3. Query the description of IPV6 interfaces
   # snmpwalk -c public -v 1 localhost ipv6IfDescr
   IPV6-MIB::ipv6IfDescr.1 = STRING: lo
   IPV6-MIB::ipv6IfDescr.3 = STRING: eth0

4. Start another network interface
   # ifup eth1

5. Check if eth1 is listed
   # cat /proc/net/if_inet6 
   00000000000000000000000000000001 01 80 10 80       lo
   fe80000000000000505400fffe0fcad9 03 40 20 80     eth0
   fe80000000000000505400fffec8188a 02 40 20 80     eth1

6. Query the description of IPV6 interfaces again
   # snmpwalk -c public -v 1 localhost ipv6IfDescr
   IPV6-MIB::ipv6IfDescr.1 = STRING: lo
   IPV6-MIB::ipv6IfDescr.3 = STRING: eth0


Actual results:
eth1 is not listed.

Expected results:
All IPV6 interfaces are listed.

Additional info:
An engineer built a test package for RHEL5, but it seems to be deleted now.
