4.2.6 WINS
If WINS is enabled, the MSS will broadcast a WINS name announcement at boot time, and
answer broadcast WINS name queries. Other hosts can locate the MSS this way. The MSS
will rebroadcast whenever its IP address or name changes.
To enable WINS, enter the following command.

4.2.7 SNMP
The MSS supports the SNMP network protocol, which allows hosts on the network to
query nodes for counters and network statistics and to change some parameters on those
nodes. The form of these requests is documented by RFC 1098. The list of items that can
be queried and/or set and the type of data used, such as integer and string, are both
documented in various Management Information Bases (MIBs). MIBs cover a variety of
things, such as counters and IP address resolution tables.
The MSS supports the following MIBs:
The MSS will respond to queries for unknown MIBs with a “not in MIB” error to the to the
requesting host.
4.2.7.1 SNMP Trap Support
The MSS will generate limited forms of three of the SNMP traps. Traps are sent to a host
when certain events occur on the MSS.
The MSS will generate a Coldstart trap when it first boots, and will send a Linkup trap
when the startupfile (if any) has been read from a host and normal operation commences.
If a startupfile has been configured but the download fails, the MSS will send an
Authentication trap. In all three cases, the trap will be directed to the IP address of the
loadhost for the MSS. If a loadhost has not been specified, the traps will not be sent.
The MSS will not generate traps other than the ones listed here.
