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).
