We have two 2921 routers (R1 and R2) and stack of 3750X-12S and 3750X-24P-S (S1), R1 Gi 0/0 goes to Gi 1/0/1, R2 Gi 0/0 goes to Gi 2/0/1 of stacked switch S1. Configuration of interfaces:
! on R1
interface GigabitEthernet0/0
ip address 192.168.40.253 255.255.255.0
glbp 1 ip 192.168.40.1
no shut
! on R2
interface GigabitEthernet0/0
ip address 192.168.40.254 255.255.255.0
glbp 1 ip 192.168.40.1
no shut
! on S1
interface GigabitEthernet 1/0/1
switchport mode access
interface GigabitEthernet 2/0/1
switchport mode access
interface Vlan 1
ip address 192.168.40.230 255.255.255.0
in logs i see this:
*Mar 1 00:09:52.780: %SW_MATM-4-WIRELESS_MAC_MOVE_DENY_NOTIF: Host 0007.b400.0103 moving from Port Gi2/0/4 to Port Gi1/0/1 as wired entry not allowed (S1)
*Mar 1 00:09:55.230: %SW_MATM-4-WIRELESS_MAC_MOVE_DENY_NOTIF: Host 0007.b400.0103 moving from Port Gi2/0/4 to Port Gi1/0/1 as wired entry not allowed (S1)
*Mar 1 00:09:58.082: %SW_MATM-4-WIRELESS_MAC_MOVE_DENY_NOTIF: Host 0007.b400.0103 moving from Port Gi2/0/4 to Port Gi1/0/1 as wired entry not allowed (S1)
*Mar 1 00:10:00.171: %SW_MATM-4-WIRELESS_MAC_MOVE_DENY_NOTIF: Host 0007.b400.0103 moving from Port Gi2/0/4 to Port Gi1/0/1 as wired entry not allowed (S1)
And the most strange thing is that S1's Gi2/0/4 port is empty, there's no connection to it.
0007.b400.0103 is GLBP virtual MAC, and when i'm turning off GLBP, errors %SW_MATM-4-WIRELESS_MAC_MOVE_DENY_NOTIF goes away.
But i have another strange thing with this particular routers and switch: 192.168.40.253 (R1) cannot ping 192.168.40.254 (R2), but each of them can ping 192.168.40.230 (S1). I think that all of this is somehow connected, but where to look?
