SW3 interface configurations: interface gigabitethernet49 In this example, the mac address table is displayed for SW3.
SW2 interface configurations: interface gigabitethernet51 Switchport trunk allowed vlan add 503,508,590 SW1 interface configurations: interface gigabitethernet51 (I spent some time trolling the Cisco pages but havent found the command yet. Show conf shows all stack members but sho mac address-table only shows the first stack member. How can I get a particular command run on the 2nd or 3rd stack member.
Switchport trunk allowed vlan 1,503,508,590 If I do a show mac address-table I get the macs for just the primary member of the stack.

Here is the current configuration for all switch-to-switch links as well as a the full mac address table for each switch.Ĭore Switch interface configurations: interface GigabitEthernet1/1/1 What might be causing this periodic flap between ports? How can I determine which switch this MAC address actually belongs When I remove the loop, The Core says the MAC is available through Po2 (The link to SW2), however SW2 says the MAC is available through Po1 (The uplink to the Core). config system interface edit 'SWFirewall' set vdom 'Firewall' set ip 8x.4y.8z.254 255.255.255.0 set allowaccess ping https ssh set type hard-switch set snmp-index 18 set secondary-IP enable config. The offending MAC address seems to be a Cisco MAC (Possible one assigned to a port group?) however I am unable to physically locate the switch to which it belongs. Hi guys, I have configured a virtual-switch aka hardware-switch and binded 4 interfaces that belong to a VDOM. %SW_MATM-4-MACFLAP_NOTIF: Host 00eb.d5f2.0b9a in vlan 1 is flapping between port Po1 and port Po2 The problem I have is that the core switch periodically logs a MAC Flap event between the links to SW1 and SW2. This will work though if the device was just booted. Tried show ip arp incl using the first 4-6 characters and got nothing. I do have I.P addresses in another area, but they are not in the spreadsheet I am working off of so I was hoping to use only the mac address. Spanning-tree seems to be functioning as expected and the interface on SW3 that connects to SW4 is put into a blocking state. The show mac address table interface x/x/x also returns nothing. The links between all switches are trunks that allow vlans 1,503,508,590

The other switches are SG300 series small business switches. (I have included a picture of the topology below). I'm working on a rather small Layer 2 network segment that contains a physical loop.
