Symptoms

On IP PMF, when running linkDisp or routeDisp, some Traffic Classification (TC) and routes are showing less traffic passing the filter or being forwarded to IXP.

Changes

PMF was upgraded to PIC 10.1.

Cause

IP PMF have:

• TC filters use VLAN filters
• Hewlett-Packard Company NC364T PCI Express Quad Port Gigabit Server Adapter
• 2.3.2-k e1000e driver

Other cards are not impacted by this problem.

This is tracked by <bug 22377895>.

Solution

Solution consist of changing MTU after TKLCmf has been started.

Quick workaround

1. As root, run the following command:
   
   for i in 'su - cfguser -c "iqt -phz -f_devName DbIpDevice" | grep eth'; do ifconfig $i mtu 2000; done
   No restart of process or service are required
2. Verify traffic is back to normal.

This workaround will be lost if pmiaMonitor is restarted in any way (pm.kill, prod.dbdown, prod.stop, ...).

To make it permanent, follow workaround below.

Permanent workaround

Workaround 1

Workaround consist of modifying TKLCmf service script so that MTU is changed after startup and before shutdown.

If in doubt, ask for Oracle support help.

1. Edit file /etc/init.d/TKLCmf
2. Add line has shown (in underline bold):
   ...
   if [ -d /tekelec/TKLCmf/runtime/run/db ]
   then
   chown -R cfguser /tekelec/TKLCmf/runtime/run/db
   fi
   for i in 'su - cfguser -c "iqt -phz -f_devName DbIpDevice" | grep eth'; do ifconfig $i mtu 2000; done
   ;;
   'stop')
   echo "Stopping the MF System"
   for i in 'su - cfguser -c "iqt -phz -f_devName DbIpDevice" | grep eth'; do ifconfig $i mtu 1500; done
   su - cfguser -c prod.dbdown
   rm -f /var/lock/subsys/TKLCmfi
   ;;
   ...
3. Verify trafic is fine after a service restart:
   1. As root, run:
      service TKLCmf stop
      service TKLCmf start

Workaround 2 (prefered)

1. As root, copy VLANWA.sh in /usr/local/sbin/
2. Correct potential copy issues:
   dos2unix /usr/local/sbin/VLANWA.sh
3. Add eXecution rights:
   chmod u+x /usr/local/sbin/VLANWA.sh
4. Add in cron:
   echo "* * * * * /usr/local/sbin/VLANWA.sh" >> /var/spool/cron/root
5. Check in /var/log/cron for execution
