hi,
i have a problem in a 3750, 3750x mixed stack. i replaced 2 pcs. 3750 with 3750x with no problem, but now we have a port config problem
IOS 12.2(55)SE1
the old config was:
interface Port-channel1
description UPLINK
switchport trunk encapsulation dot1q
switchport mode trunk
switchport nonegotiate
FastEthernet 2/0/1 - 48
description **ACCESS PORT**
switchport access vlan 301
switchport mode access
storm-control broadcast level 10.00
storm-control action trap
no cdp enable
no cdp tlv server-location
no cdp tlv app
spanning-tree portfast trunk
spanning-tree bpduguard enable
GigabitEthernet 2/0/1 - 4
description **UPLINK**
switchport trunk encapsulation dot1q
switchport mode trunk
switchport nonegotiate
channel-group 1 mode active
----
then we replaced this switch 2 with the new 3750X with the 4port Gigabit Module
new config:
GigabitEthernet 2/0/1 - 48
-> access Ports (same as old for access ports)
GigabitEthernet 2/1/1 - 4
-> uplink ports in the port-channel group 1 (same as old for uplink)
but the old config from the first 4gigabit ports was not deleted -> now i became following errors:
000096: Apr 10 06:57:24: %EC-5-CANNOT_BUNDLE2: Gi2/0/1 is not compatible with Gi2/1/1 and will be suspended (Broadcast suppression: Level of Gi2/0/1 is 10.00%, 10.00%. Level of Gi2/1/1 is not configured.) (switch2)
000097: Apr 10 06:57:24: %EC-5-CANNOT_BUNDLE2: Gi2/0/4 is not compatible with Gi2/1/3 and will be suspended (Broadcast suppression: Level of Gi2/0/4 is 10.00%, 10.00%. Level of Gi2/1/3 is not configured.) (switch2)
000098: Apr 10 06:57:24: %EC-5-CANNOT_BUNDLE2: Gi2/0/3 is not compatible with Gi2/1/3 and will be suspended (Broadcast suppression: Level of Gi2/0/3 is 10.00%, 10.00%. Level of Gi2/1/3 is not configured.) (switch2)
it seems that the old config, which was associated to the gigabit 2/0/1 - 4 uplink ports, is now active on the new switch - but these are now configured as access ports.
i tried to remove the Portchannel 1 -> reassociated to the Uplink ports -> no changes on this behaviour
i tried default interface giga 2/0/1...4 -> not ok
i replaced the switches when the whole stack was running... should i try to reload the whole stack?
other ideas?
thanks.
