1. I have the attached Network Switch setup in our office.i am just new to this place and trying to understand the topology.we have more than 25 vlans in our network and VTP enbaled in it.manually spanning-tree root switch has not been configured hence it took the lowest mac-address bearing switch as its root switch which is very old switch. do we face any issue/latency in reaching other subnet through this root switch?
2. Right now we dont have IP phones in our network. we use Nortel PBX with phone. now our company has decided to implement Avaya IP phones in our network. with this current set up can i implement IP phones in our network.can we enable QOS in this switches? Do we need to create separate Vlan for Voice?
Please suggest some ideas and configurations
