This command shows alias information collected by the Node Alias feature for the specified MAC address. 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. |
| mac | Designates displaying node aliases with the specified MAC address. |
| mac_address | Specifies for which MAC address to display node alias information. |
| protocol | Designates that you want to see only alias information discovered by a particular protocol (default is all protocols). |
| protocol_name | Specifies the protocol that you want to see alias information discovered by: ip, ipv6, ospf, bgp, bootps, bootpc, vrrp, dhcps, dhcpc, bpdu, udp, mdns, llmnr, or ssdp. |
| ports | Designates that you want to only see node alias information for the selected ports (default is all ports). |
| port_list | Specifies for which ports to show node alias information. Designated as a port list separated by comma (,) or dash (-). |
| all | (Default) Shows node alias information for all ports. |
If a specific protocol is not selected, information appears for all protocols. If specific port(s) are not selected, information appears for all ports.
The following example shows node alias information for MAC address 20:b3:99:5e:b5:e5 and on all ports, discovered by all protocols:
# show nodealias mac 20:b3:99:5e:b5:e5 Port MAC Address Alias ID Time Last Learned VID Protocol Source IP ----- ----------------- ---------- ------------------- ---- -------- --------------- 10 20:b3:99:5e:b5:e5 716168878 2016-06-24 13:23:57 1 ip 10.50.0.2
