OBJECT-TYPE

The tmnxPtpPeerConfigTable consists of peer configuration information.

OBJECT-TYPE

The tmnxPtpPeerConfigEntry contains information pertaining to an individual PTP 1588 peer. Individual PTP peers are identified by the IP address of the peer PTP clock. If tmnxPtpClockClockType is 'ordinarySlave (1)', entries may be created and deleted via SNMP set operations using tmnxPtpPeerRowStatus. The tmnxPtpPeerRemoteMaster attribute will be created with a value of 'true', and the tmnxPtpPeerRemoteSlave attribute will be created with a value of 'false'. Neither or these attributes may be subsequently changed. These entries correspond to PTP grandmaster or boundary clocks providing timing information to the local clock. In order to delete an entry, tmnxPtpPeerAdminState must first be set to 'outOfService (3)'. If tmnxPtpClockClockType is 'ordinaryMaster (2)', entries are automatically created upon receipt of PTP signaling packets requesting unicast transmission of PTP packets. Entries cannot be created or deleted via SNMP set operations. These entries correspond to PTP slave boundary clocks receiving timing information from the local clock. These entries are created by the system with tmnxPtpPeerRemoteMaster set to 'false' and tmnxPtpPeerRemoteSlave set to 'true'. If tmnxPtpClockClockType is 'boundary (3)', entries corresponding to grandmaster or boundary PTP clocks providing timing to the local clock may be created and deleted via SNMP set operations, in the same manner as when tmnxPtpClockClockType is 'ordinarySlave (1)'. As well, entries corresponding to slave or boundary PTP clocks receiving timing from the local clock may be automatically created by the system, in the same manner as when tmnxPtpClockClockType is 'ordinaryMaster (2)'. For an individual entry, the value of tmnxPtpPeerRemoteMaster along with tmnxPtpPeerRemoteSlave indicates the direction of flow of timing information between the local PTP clock and the peer PTP clock. There are three cases: 1) If tmnxPtpPeerRemoteMaster is 'true', and tmnxPtpPeerRemoteSlave is 'false', the peer PTP clock is providing timing to the local PTP clock. In this case, PTP Announce, Sync, and Delay Reponse packets are sent from the peer PTP clock to the local PTP clock, and PTP Delay Request packets are sent from the local PTP clock to the peer PTP clock. This type of PTP peer may exist when tmnxPtpClockClockType is either 'ordinarySlave (1)' or boundary (3)'. 2) If tmnxPtpPeerRemoteMaster is 'false', and tmnxPtpPeerRemoteSlave is 'true', the local PTP clock is providing timing to the peer PTP clock. In this case, PTP Announce, Sync, and Delay Reponse packets are sent from the local PTP clock to the peer PTP clock, and PTP Delay Request packets are sent from the peer PTP clock to the local PTP clock. This type of PTP peer may exist when tmnxPtpClockClockType is either 'ordinaryMaster (2)' or boundary (3)'. 3) If tmnxPtpPeerRemoteMaster and tmnxPtpPeerRemoteSlave are both set to 'true', the local clock and remote PTP clock have a peer relationship. Timing information may flow in either direction, depending on the decision of the PTP Best Master Clock Algorithm running on each PTP clock. This type of PTP peer may only exist when tmnxPtpClockClockType is 'boundary (3)'. When tmnxPtpClockClockType is 'boundary (3)', a peer entry may be changed from one that is only receiving timing from the local clock, to one that may either receive or provide timing, by setting tmnxPtpPeerRemoteMaster to 'true'.

OBJECT-TYPE

The value of tmnxPtpPeerIpAddrType specifies the type of address of the PTP 1588 peer. This object represents the first index in the table.

OBJECT-TYPE

The value of tmnxPtpPeerIpAddress specifies the address of the PTP 1588 peer. This object represents the second index in the table.

OBJECT-TYPE

The value of tmnxPtpPeerRowStatus specifies the row status of the PTP 1588 peer. This object controls the creation and deletion of peer PTP grandmaster and boundary clocks that may provide timing to the local PTP clock. These PTP peers may only be created when tmnxPtpClockClockType is set to 'ordinarySlave (1)' or 'boundary (3)'. For these peers, tmnxPtpPeerRemoteMaster will be set to 'true'. Before deleting one of these PTP peers, tmnxPtpPeerAdminState must be set to 'outOfService (3)'. Peers that correspond to slave or boundary PTP clocks that may receive timing information from the local clock can not be created or deleted by the use of this object. Instead, they are dynamically created by the system through the operation of the Precision Time Protocol.

If tmnxPtpClockClockType is 'ordinaryMaster (2)', all entries in this table will have tmnxPtpPeerRemoteMaster set to 'false', and it cannot be changed. If tmnxPtpClockClockType is 'boundary (3)', there may be entries in this table with tmnxPtpPeerRemoteMaster set to 'false', indicating that the local clock is only providing timing information to the remote PTP peer. This peer may be changed to one that may either receive or provide timing, by setting tmnxPtpPeerRemoteMaster to 'true'. When the value of this object is 'true', a corresponding row in the tmnxPtpPeerMasterStatusTable will exist for this peer.

OBJECT-TYPE

The value of tmnxPtpPeerRemoteSlave specifies whether or not the peer is acting as a remote slave or boundary clock that may be receiving timing information from the local clock. Remote slave clocks are learned by the local clock upon reception of PTP signaling packets, and cannot be configured via SNMP set operations. If tmnxPtpPeerRemoteSlave is 'true', it indicates that the local PTP clock may provide timing information to the PTP peer. If tmnxPtpClockClockType is 'ordinarySlave (1)', all entries in this table will have tmnxPtpPeerRemoteSlave set to 'false'. If tmnxPtpClockClockType is 'ordinaryMaster (2)', all entries in this table will have tmnxPtpPeerRemoteSlave set to 'true'.

If PTP event packets are transmitted out an interface with tmnxPtpVRtrIfAdminState set to 'outOfService(3)', the value is 'cpm(2)'.

The value may only be configured to 'inService(2)' if all of the following are true: 1. An IPv4 address is configured against the interface. 2. An Ethernet physical port (or VLAN tag on an Ethernet physical port) has been associated with the interface. 3. The Ethernet port associated with the interface must not be configured for WAN mode. In other words, the tmnxPortEtherXGigMode attribute for the port must be either 'notApplicable' or 'lan'. 4. The MDA associated with the interface has synchronous Ethernet enabled. In other words, the tmnxMDASynchronousEthernet attribute for the MDA must be 'enabled'. 5. The port associated with the interface is on an IOM that supports the hardware assist configuration. 6.
