To define the SNMP engine ID:
STEP 1 Click SNMP > Engine ID.
STEP  2 Choose which to use for Local Engine ID.
• Use Default—Select to use the device-generated engine ID. The default 
engine ID is based on the device MAC address, and is defined per standard 
as:
- First 4 octets—First bit = 1, the rest is the IANA enterprise number. 
- Fifth octet—Set to 3 to indicate the MAC address that follows.
- Last 6 octets—MAC address of the device.
• None—No engine ID is used.
• User Defined—Enter the local device engine ID. The field value is a 
hexadecimal string (range: 10 - 64). Each byte in the hexadecimal character 
strings is represented by two hexadecimal digits.
All remote engine IDs and their IP addresses are displayed in the Remote Engine 
ID table.
STEP  3 Click Apply. The Running Configuration file is updated.
The Remote Engine ID table shows the mapping between IP addresses of the 
engine and Engine ID. To add the IP address of an engine ID:
STEP  4 Click Add. Enter the following fields:
• Server Definition—Select whether to specify the Engine ID server by IP 
address or name.
• IP Version—Select the supported IP format.
• IPv6 Address Type—Select the IPv6 address type (if IPv6 is used). The 
options are:
- Link Local—The IPv6 address uniquely identifies hosts on a single 
network link. A link local address has a prefix of FE80, is not routable, and 
can be used for communication only on the local network. Only one link 
local address is supported. If a link local address exists on the interface, 
this entry replaces the address in the configuration.
- Global—The IPv6 address is a global Unicast IPV6 type that is visible and 
reachable from other networks.
