: The Nexus 7000 supports dual supervisor modules to provide 1 1 redundancy for the control and management plane.
Only one of the supervisor modules is active at any given time, while the other acts as a standby backup. In NX-OS, the HSRP feature needs to be enabled before it can be used.
VTP helps you simplify management of the VLAN database across multiple switches.
VTP is a Cisco-proprietary protocol and is available on most of the Cisco switches. To answer this question, let’s discuss a real and popular network topology.
Well, it will surely become a daunting task to add a new VLAN like this.When VTP pruning is enabled, traffic will not be passed to another switch across a trunk link unless that switch has ports configured for a given VLAN.For example, imagine Switch A has VLANs 1, 2, and 3 configured, and a trunk link to Switch B.If VTP pruning is enabled, and Switch B has no ports on VLAN 2, traffic for VLAN 2 will not passed to it.VLAN pruning is enabled using the command vtp pruning enable.
