enable nodealias protocol
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, BGP, VRRP, 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
- ARP is categorized under IP.
- UDP entry is created when destination IP address is broadcast.
- BPDU means STP 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
