MIBs
120
3.
Obtain the current value of certain parameters and simultaneously
change the value of other parameters - the NMS uses the SetRequest
PDU, and the switch responds with a GetResponse PDU. For the
parameters which are being obtained rather than changed, the NMS
must use the ASN.1 NULL value with the SetRequest PDU.
4.
Provide notification of significant events - the switch uses the Trap
PDU and/or the Get Response PDU. The NMS uses the Set Request
PDU to control the frequency that the switch may send Trap PDUs.
TCP/IP MIB-II
Your switch supports TCP/IP MIB-II, as defined by Management
Information Base for network management of TCP/IP-based internets
MIB-II, RFC 1213 (K. McCloghrie, editor), dated March 1991. The MIB is
divided into groups of parameters. The individual groups are described in
the subsections below. You may want to refer to the actual TCP/IP MIB,
since this document paraphrases the standard MIB in order to provide
switch-related descriptions.
Address
Translation Group
TCP/IP Address Translation Group parameters are minimally supported
(i.e., for any parameter in this group, the switch returns a GetResponse
with a noSuchName ErrorStatus). It is anticipated that the Address
Translation Group will be deleted from TCP/IP MIB III, since there will be
separate address translation tables for every type of network protocol
(indeed, TCP/IP MIB II already defines the IP Address Translation Table).
IP Routing Table
The TCP/IP IP routing table contains the routing information for each
route currently known. When adding a row, the entire row must be
specified, except for the following defaults:
❑
ipRouteDest is obtained from the row's instance identifier.
❑
ipRouteMetric1 defaults to 0.
❑
ipRouteMetric2 defaults to sxadminStaticPreference.
❑
ipRouteMetric3 through ipRouteMetric5 default to -1.
❑
ipRouteNextHop is obtained from the row's instance identifier.
❑
ipRouteType defaults to “direct” if ipRouteNextHop is not
specified, or if ipRouteNextHop is specified and it, combined with
ipRouteMask, equals the same network as that defined by
ipRouteDest.
❑
ipRouteProto defaults to “netmgmt”.
❑
ipRouteMask defaults to the standard network class mask based
on the row's instance identifier (except 255.255.255.255 is used if
the row's instance identifier contains a non-zero host portion).
