I've got a 3Com 2226 switch. It has a trunk connection uplink to another switch (Actually a Cat 6509). I've connected an 877 router to one of the normal, non-trunk, ports on the switch.
Whenever I plug in the router, I get:
*Mar 1 00:18:01.679: %SPANTREE-7-RECV_1Q_NON_TRUNK: Received 802.1Q BPDU on non trunk FastEthernet0 VLAN1.
*Mar 1 00:18:01.679: %SPANTREE-7-BLOCK_PORT_TYPE: Blocking FastEthernet0 on VLAN1. Inconsistent port type.PVST+: restarted the forward delay timer for FastEthernet0
Either I'm doing something wrong on the 3Com switch, or doing something wrong on the 877 router. (At this stage the router has no config apart from an IP address on VLAN1) Can anyone point me in the right direction ?
