Multicast Source Discovery Protocol (SDP) MIB
The Multicast Source Discovery Protocol (MSDP) MIB feature adds support in Cisco IOS software for
the MSDP MIB. This MIB describes objects used for managing MSDP operations using Simple Network
Management Protocol (SNMP). Documentation for this MIB exists in the form of an Internet Draft titled
“Multicast Source Discovery Protocol MIB” (draft-ietf-msdp-mib-03.txt) and is available through the
Internet Engineering Task Force (IETF) at http://www.ietf.org. For additional information, refer to the
MSDP MIB feature module on Cisco.com.
Network Time Protocol (NTP) MIB
The Network Time Protocol (NTP) is used to synchronize timekeeping among a set of distributed time
servers and clients. The Cisco NTP MIB enables users to remotely monitor an NTP server using the
Simple Network Management Protocol (SNMP), provided the MIB itself is implemented on that server.
Use of the NTP MIB to monitor the NTP status of routing devices is accomplished using software on a
network management system (NMS). There are no new or modified Cisco IOS software commands
associated with this feature.
The Cisco implementation of the NTP MIB is based on NTP version 3 (RFC-1305). The MIB objects
are all read-only. SNMP requests are processed by reading the corresponding variables from the NTP
subsystem and returning them in the response. The NTP MIB defines a set of NTP server system objects,
including an NTP server peers table and an NTP server filter register table.
For complete details on the Cisco implementation of the NTP MIB, refer to the MIB file itself at
ftp://ftp.cisco.com/pub/mibs/v2/CISCO-NTP-MIB.my.
SNMP Enhancements to CISCO-DOCS-EXT-MIB
Commencing with Cisco IOS Release 12.2(4)BC1, the following attributes have been added to
CISCO-DOCS-EXT-MIB to provide information about the Unsolicited Grant Service (UGS) allocation
on the upstream interfaces:
• “cdxIfUpChannelNumActiveUGS” returns the number of active UGS flows currently allocated on
the upstream.
• “cdxIfUpChannelMaxUGSInLastOneHour” returns the maximum number of UGS flows allocated
on the upstream in the last hour.
• “cdxIfUpChannelMinUGSInLastOneHour” returns the minimum number of UGS flows allocated
on the upstream in the last hour.
• “cdxIfUpChannelAvgUGSInLastOneHour” returns the average number of UGS flows allocated on
the upstream in the last hour.
• “cdxIfUpChannelMaxUGSInLastFiveMins” returns the maximum number of UGS flows allocated
on the upstream in the last five minutes.
• “cdxIfUpChannelMinUGSInLastFiveMins” returns the minimum number of UGS flows allocated
on the upstream in the last five minutes.
• “cdxIfUpChannelAvgUGSInLastFiveMins” returns the average number of UGS flows allocated on
the upstream in the last five minutes.
