I have a weird problem that just popped yesterday. We run port security on all of our switches ports connected to servers, the mac addresses are hard-coded on each server interface. Yesterday 8-10 ports on 3 different switches were shut down for port security at the same time. When looking at the port status the last-src-addr and the secure-src-address were still the correctly configured mac. The boxes are 6500s running cat6000-sup2k9.8-5-6.bin. The ports are on different blades and the NICs are from different manufacturers.
I ended up having to clear port security on all of the ports and enabling them again. Everything was good yesterday afternoon but I experienced the same problem again this morning.
Anyone else experience this problem? Any fix action?
Thanks in advance for any assistance!
