disable nodealias protocol
Description
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.
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 disabling 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 disabling all protocols. |
Default

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).
