Hello, I am confused with this statement:
According to Cisco Press book, CCNP SWITCH: Offical Certification Guide, by David Hucaby, if a switch can't support 1024 unique MAC addresses for its own use, the extended system ID is always enabled by default. Otherwise, the traditional method is enabled by defaulth
Does this mean that if the switch does not suppoort 1024 unic MAC addresses (it supports less than 1024) it will use Extended System ID, but if it does support 1024 it will use the Traditional method?
I am confused because I read these somewhere else: ...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.
I just need a clearer explanation please!!!!
