Hi, I have seen strange behaviour between two palo alto firewalls. I have pair of PA-3020 and Pair of PA-500 in Active/standby scenario. They serve two different networks but to provide interconnect between two networks they (Eth 1/3) are connected to Cisco Nexus switch via FEX (VLAN 129). Has anyone seen a case where two different models of the firewall connected via same vlan share same mac address? admin@CFWL02(active)> show arp all interface ip address hw address port status ttl -------------------------------------------------------------------------------- ethernet1/3.129 10.224.63.33 00:1b:17:00:01:12 ethernet1/3 c 1487 admin@MFWL02(active)> show arp all interface ip address hw address port status ttl -------------------------------------------------------------------------------- ethernet1/3.129 10.224.63.36 00:1b:17:00:01:12 ethernet1/3 c 1627 L2S01# sh mac address-table vl 129 Legend: * - primary entry, G - Gateway MAC, (R) - Routed MAC, O - Overlay MAC age - seconds since last seen,+ - primary entry using vPC Peer-Link VLAN MAC Address Type age Secure NTFY Ports/SWID.SSID.LID ---------+-----------------+--------+---------+------+----+------------------ + 129 001b.1700.0112 dynamic 0 F F Po1000 L2S01# sh mac address-table vl 129 Legend: * - primary entry, G - Gateway MAC, (R) - Routed MAC, O - Overlay MAC age - seconds since last seen,+ - primary entry using vPC Peer-Link VLAN MAC Address Type age Secure NTFY Ports/SWID.SSID.LID ---------+-----------------+--------+---------+------+----+------------------ * 129 001b.1700.0112 dynamic 10 F F Eth122/1/47 I will appreciate your help if you advise me.
