MS NLB failing on 6509 after reboot

[neil_titchener]

Hi, We have an issue where MS NLB fails after a switch reboot i.e. the arp entries no longer exist and the only way around this is by removing and reapplying the configuration.  I believe our configuration isn't actually correct but I wanted to know if anyone has experienced the same issue on the same version of software or even the same configuration.

Software version is 15.0(1)SY6, running in VSS mode

Actual configuration is:

Global config

arp 172.24.1.1 03bf.ac18.1234 ARPA

mac address-table static 03bf.ac18.1234 vlan 2 interface Port-channel1

I believe the configuration should be:

Interface Vlan 2

arp 172.24.1.1 03bf.ac18.1234 ARPA

exit

mac address-table static 03bf.ac18.1234 vlan 2 interface Port-channel1

Thanks in advance

Hi,

Looking at this document, all configs are global and not under any SVIs.

If this does not work after every reboot, you may want to open a ticket with TAC as it may be a bug.
