UCS (Unified Communication Server) Fabric Interconnect.

2000 series FEX are childs to 5000, 6000, 7000 and UCS F.I. parents.

These all support FCoE (Fibre Channel Over Ethernet). 10Gbps and more.

DTP concept if gone in NX-OS.

Vtp pruning can be used to automatically prune the vlans which required vtp to be running or you

can manually prune by using switchport allowed vlan.

NX-OS(config)#feature vtp !(is not ON by default)

Remember switches need to be connected using 802.1q trunks for vtp to work.

To reset the vtp revision number simply rename the vtp domain name.

AD of static route is 1.

Default route or gateway of last resort.

NS-OX(config)#feature ospf

Really quick convergence time happens with eigrp due to feasible successor routes.

You can use prefix notation in ACLs and interface configuration now on NX-OS.

NS-OS(config)#ip access-list test1

NS-OS(config-acl)#permit tcp 172.16.0.0/16 any eq 80

NS-OS(config-acl)#permit tcp 172.16.0.0/16 any eq 25
