The MIB module for managing SRCP(Simple Resource Coordination Protocol) implementations. SRCP is a resource coordination protocol used between a MGC(Media Gateway Controller) and a MG(Media Gateway). SRCP MIB is applicable to both controllers (SRCP clients) and gateways (SRCP servers).
MGMIB: This is the short name used for CISCO-WAN-MG-MIB in this MIB.
DisplayStringRepresents textual information taken from the NVT ASCII
character set, as defined in pages 4, 10-11 of RFC 854.
To summarize RFC 854, the NVT ASCII repertoire specifies:
- the use of character codes 0-127 (decimal)
- the graphics characters (32-126) are interpreted as US ASCII
- NUL, LF, CR, BEL, BS, HT, VT and FF have the special meanings specified in RFC 854
- the other 25 codes have no standard interpretation
- the sequence 'CR LF' means newline
- the sequence 'CR NUL' means carriage-return
- an 'LF' not preceded by a 'CR' means moving to the same column on the next line.
- the sequence 'CR x' for any x other than LF or NUL is illegal. (Note that this also means that a string may end with either 'CR LF' or 'CR NUL', but not with CR.)
Any object defined using this syntax may not exceed 255 characters in length. SIZE (1..64) · OCTET STRING · hint 255a
The name of the SRCP protocol version for exmaple SRCP 1.0.2. If MGMIB is supported, this name corresponds to mgProtocolName (defined in CISCO-WAN-MG-MIB MIB) in an entry to mgSupportedProtocolTable.
srcpPortNumber
1.3.6.1.4.1.351.150.11.1.1.2
Integer32 (1025..65535)
This object is used to configure the UDP port used for SRCP on the system (local UDP port). It is configurable only if the system is in a locked or disabled state (i.e If MGMIB Is supported, mgAdministrativeState(defined in CISCO-WAN-MG-MIB MIB) should be 'locked' before the UDP port can be configured).
srcpRequestTimeOut
1.3.6.1.4.1.351.150.11.1.3.1
Integer32 (1..10000) · milliseconds
This object specifies the minimum timeout value.
This value along with srcpRequestMaxTimeout and srcpRequestRetries is used to determine the exponential retry interval for retransmitting unacknowledged SRCP messages.
It is the responsibility of the requesting entity to provide suitable timeouts for all outstanding commands, and to retry commands when timeouts exceeded.
The default value of this object is 500 milliseconds.
When the value of this object changes srcpAdminObjects group changed trap will be sent as specify by vismConfigChangeTypeBitMap in CISCO-VISM-MODULE-MIB.
srcpRequestRetries
1.3.6.1.4.1.351.150.11.1.3.2
Integer32 (0..10)
This object specifies the number of retries for a SRCP request that exceeds timeout. It is the responsibility of the requesting entity to provide suitable timeouts for all outstanding commands, and to retry when times out.
The default value of this object is 3.
When the value of this object changes srcpAdminObjects group changed trap will be sent as specify by vismConfigChangeTypeBitMap in CISCO-VISM-MODULE-MIB.
srcpRequestMaxTimeout
1.3.6.1.4.1.351.150.11.1.3.3
Integer32 (1..10000) · milliseconds
This object specifies the maximum timeout value.
This timer value is used along with srcpRequestTimeOut and srcpRequestRetries to determine the exponential retry interval for retransmitting unacknowledged SRCP messages.
The value of this timer has to be greater than or equal to srcpRequestTimeOut.
The default value of this object is 500 milliseconds.
When the value of this object changes srcpAdminObjects group changed trap will be sent as specify by vismConfigChangeTypeBitMap in CISCO-VISM-MODULE-MIB.
Table details
srcpPeerTable
1.3.6.1.4.1.351.150.11.1.1.3
Index: srcpPeerId
This is a table which is used to provision peer-specific SRCP configuration and administration information. Each table entry corresponds to an SRCP peer as identified by its domain name(srcpPeerName).
srcpPeerId
1.3.6.1.4.1.351.150.11.1.1.3.1.1
Integer32 (1..65535)
This object identifies the SRCP peer and serves as index to this table. If MGMIB is supported, this is the same as the mgcNumber(defined in CISCO-WAN-MG-MIB MIB) from the mgcTable.

Any object defined using this syntax may not exceed 255 characters in length. SIZE (1..64) · OCTET STRING · hint 255a
This object identifies the name of the SRCP peer. If MGMIB is supported, this is the same as the mgcName from the mgcTable.
srcpPeerPortNumber
1.3.6.1.4.1.351.150.11.1.1.3.1.3
Integer32 (1025..65535)
This object is used to configure the UDP port of the SRCP peer.
srcpPeerHeartbeatInterval
1.3.6.1.4.1.351.150.11.1.1.3.1.4
Integer32 (0..65535) · milliseconds
This object is used to configure the length of the heartbeat interval, in milliseconds. The heartbeat interval indicate when the GW(Gateway) is expected to receive a heartbeat from a specific peer or MGC group. If value is 0, heartbeat for this peer is not monitored. The heartbeat interval less than 100 is not allowed (except 0).
If MGC Redundancy is supported, this object is not effective. Instead, the user should use srcpPeerGrpHeartbeatInterval.
srcpPeerTimeSinceHeartbeat
1.3.6.1.4.1.351.150.11.1.1.3.1.5
Integer32 (0..2147483647) · milliseconds
The time since the last heartbeat was received, in milliseconds. This represents the difference between the current time and the last time an SRCP command was received.
A value of 0 shall be returned if the heartbeat is not monitored. Even if the heartbeat is monitored, a value of 0 shall be returned if any of the following is true:
i) The system is locked or disabled (as indicated by
mgAdministrativeState). ii) The srcpPeer is unassociated as indicated by mgcAssociationState(defined in CISCO-WAN-MG-MIB MIB).
If MGC Redundancy is supported, this object is not effective. Instead, the user should use srcpPeerGrpTimeSinceHeartbeat.

This object is used to configure the maximum UDP PDU(Protocol Data Unit) size, in octets, that may be used for SRCP communications with the peer.
This value may not be configurable for all agents.
If MGC Redundancy is supported, this object is not effective. Instead, the user should use srcpPeerGrpMaxPduSize.
srcpPeerGrpParamTable
1.3.6.1.4.1.351.150.11.1.1.4

This table is used to provision SRCP parameters for an MGC Redundancy group. MGCs can be configured as part of MGC Redundancy groups. This feature allows for redundant call agents.
Each table entry corresponds to an SRCP peer entry that is identified by the MGC Redundancy group number.
This is the MGC group number. A group can contain more than 1 MGC. So for a group containing more than 1 MGC, there will be more than 1 row of this table that will have a common group number.

Integer32 (0..2147483647) · milliseconds
The time since the last heartbeat was received, in milliseconds. This represents the difference between the current time and the last time an SRCP command was received.
A value of 0 shall be returned if the heartbeat is not monitored. Even if the heartbeat is monitored, a value of 0 shall be returned if any of the following is true:
i) The system is locked or disabled (as indicated by
mgAdministrativeState). ii) The stateChangeNtfy flag is disabled for the srcpPeer Group (as indicated by mgcRedundancyGrpStateChangeNtfy of CISCO-WAN-MGC-REDUN-MIB).

Index: srcpStatsPeerIpAddress
This table contains SRCP statistics information since reset. SRCP statistics are kept in this table, with each table entry containing the statistics of SRCP messages that communicated with a peer at a specific IP address of the peer.
It differs from the SRCP peer table which maintains information on a per call agent basis as identified by their domain names.
