Broadcasting Same Mac Address from Both Ports
Affected: PE 6850 (two different servers)
OS: rhel4-u3-x86_64-es (fully patched)
Symptom: Errors on eth0, slow traffic, frequent connection drops.
Other than the connect/disconnect messages, nothing is being logged by syslog.
eth0 - 10.1.1.10 0013.7241.5cdb
eth1 - 10.1.1.11 0013.7241.5cdc
On the network side, both broadcasting the same MAC address. Notice that the router is reporting both ethernet devices as having a MAC ending in "b", whereas the OS is reporting them as "c" and "b".
router11>sho ip arp | incl 10.1.1.11
Internet 10.1.1.11 79 0013.7241.5cdb ARPA Vlan185
router11>sho ip arp | incl 10.1.1.10
Internet 10.1.1.10 0 0013.7241.5cdb ARPA Vlan185
These are very typical RHEL builds and we have done nothing untoward. After banging out heads against the wall for some time, the only solution we've come up with so far is to disable eth1, which fixes the issue completely.
Anybody ever seen this before? Any suggestions on what might be causing it or what might be a fix?
