enable nodealias protocol

enable nodealias protocol [protocol_name | all]

Description

This command designates the specific protocols detected for the Node Alias feature. Node Alias discovers information about the end systems on a per-port basis. Information from packets from end systems, such as VLANID, source MAC address, source IP address, protocol, etc. are captured in a database that can be queried.

Syntax Description

nodealias Node Alias feature that maps source IP address, MAC address, host name, and protocol on a per port basis.
protocol Designates selection of protocols to detect.
protocol_name Specifies enabling a protocol to detect (one at a time). The following protocols are enabled by default: IPv4, IPv6, OSPF (Open Shortest Path First), BGP (Border Gateway Protocol), VRRP (Virtual Router Redundancy Protocol), DHCPS, DHCPC, BOOTPS, BOOTPC, UDP, BPDU, LLMNR, SSDP, and mDNS.
any Specifies enabling all Node Alias-supported protocols.

Default

The following protocols are enabled by default: IPv4, IPv6, OSPF, BGP, VRRP, DHCPS, DHCPC, BOOTPS, BOOTPC, UDP, BPDU, LLMNR, SSDP, and mDNS.
Note

Note

  • ARP is categorized under IP.
  • UDP entry is created when destination IP address is broadcast.
  • BPDU means STP (Spanning Tree Protocol) and GVRP frames.

Usage Guidelines

By default, the following protocols are enabled (IPv4, IPv6, OSPF, BGP, VRRP, DHCPS, DHCPC, BOOTPS, BOOTPC, UDP, BPDU, LLMNR, SSDP, mDNS). You can optionally disable any of these protocols (and then enable them back if desired).

Example

The following example specifically enables BGP to be detected:

enable nodealias protocol bgp
