Experts,

What is this message all about "00:00:15: %SPANTREE-5-EXTENDED_SYSID: Extended SysId enabled for type vlan" ?

Thanks.

Re: show log message

Releases 12.1(8a)E and later support a 12-bit extended system ID field as part of the bridge ID (see Table 11-2). Chassis that support only 64 MAC addresses always use the 12-bit extended system ID. On chassis that support 1024 MAC addresses, you can enable use of the extended system ID. STP uses the VLAN ID as the extended system ID
