I have a brand new switch WS-C2960G-48TC-L with ios "flash:c2960-lanbase-mz.122-25.SEE2/c2960-lanbase-mz.122-25.SEE2.bin"
and when i configure vlan trunks with any other type of switches (2950,2960,2970) the port led on both switches changes continusly from green to amber. The trunk seems that it's working with no CRC errors or interface resets.
Anyone that can help on this. Cisco said that this is a link-fault indication nothing else.
