This command designates the specific protocols to remove from the list of detected protocols 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.
| 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 disabling 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 disabling all protocols. |
Note
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).
The following example disables BGP from being detected:
disable nodealias protocol bgp
