Cisco Configuration Guidelines for VC Uplink Ports
VLAN Tagged VC Uplink (Shared Uplink Set) Configuration Guidelines:
Action Command
• Set VLAN encapsulation to 802.1Q “switchport trunk encapsulation dot1q”
• Set the switch port mode to trunk “switchport mode trunk”
• Enable PortFast “spanning-tree portfast trunk”
• Disable DTP “switchport nonegotiate”
• Enable autonegotiation “speed auto” and “duplex auto” (if
applicable)
• Enable LLDP “lldp transmit” and “lldp receive” (if
supported)
• -Optional- Enable BPDUGuard “spanning-tree bpduguard enable”
Untagged
VC Uplink (regular VC Network\vNet) Configuration Guidelines:
Action Command
• Set the Cisco switch port mode to
access
“switchport mode access”
• Enable PortFast “spanning-tree portfast”
• Disable DTP “switchport nonegotiate”
• Enable autonegotiation “speed auto” and “duplex auto” (if
applicable)
• Enable LLDP “lldp transmit” and “lldp receive” (if
supported)
• -Optional- Enable BPDUGuard “spanning-tree bpduguard enable”
Port Channeling Configuration Guidelines:
Action Command
• Set the interface channel protocol
to LACP
“channel-protocol LACP”
• Assign interface to a port channel
(where X is the same for all Cisco
ports in the same group) and
enable LACP
“channel-group X mode active”
Or
“channel-group X mode passive”
If the port channel is untagged (access mode), refer to the configuration guidelines
above for a Untagged VC uplink. Make sure to apply commands to the Port Channel
interface and not just the port interfaces.
If the port channel is tagged (VLAN trunk mode), refer to the configuration guidelines
above for a Tagged VC uplink. Make sure to apply commands to the Port Channel
interface and not just the port interfaces.
