PE to CE Pings remote ping group

The PE to CE Pings default remote ping group is used by MPLS Manager to generate all possible PE-to-CE pings in a VPN, and to monitor and analyze the ping test results to determine PE-to-CE reachability. It has a single, valid setting named PE to CE Ping Settings.

This setting determines (1) the creation of remote ping entries in the SNMP Ping MIB tables on the source PEs and (2) the polling intervals that are used by MPLS Manager to monitor the ping test results. MPLS Manager monitors the ping test results by probing the Ping MIB tables on the source PEs.

By default, each PE in a VPN pings every remote CE or multi-VRF CE in the VPN. A remote CE is a CE that is attached to a peer PE.

PE to CE Ping Settings parameters and their values lists the PE to CE Ping Settings parameters.

Table 1. PE to CE Ping Settings parameters and their values

Parameter	Values	Description
AnalysisMode	ENABLED,DISABLED Default: DISABLED	Enables or disables the MPLS Manager triggering of PE-to-CE pings and the subsequent polling and analysis of the polled ping test results.
Classification	PE_TO_REMOTE_CEPE_TO_LOCAL_CE Default: PE_TO_REMOTE_CE	Sets the type of ping to execute: Source PEs to destination Remote CEs (CEs that are attached to the peer PEs of a source PE) on a per VPN basis. Source PEs to destination Local CEs (CEs that are attached directly to a source PE) on a per VPN basis.
DestinationIP	Regular expression Default: *.*.*.* (By default, all loopback IP addresses of a destination CE are selected.)	Specifies the wildcard expression to use to select the loopback IP addresses of the destination CEs for PE-to-CE pings. An example entry is 163.*.*.*, which would limit the selected loopback IP addresses to just those beginning with 163.
DestinationName	Regular expression Default: * (By default, all CEs are selected as destination CEs.)	Specifies the wildcard expression to use to select the destination CEs for PE-to-CE pings. An example entry is C*, which would limit the selected destination CEs to just those that have names beginning with C.
DestinationType	SNMP_ADDRESS,ALL_IPS Default: SNMP_ADDRESS	Determines whether just the SNMP address of the destination CE is to be pinged or whether all IPs of the destination CE are to be pinged.
PacketSize	0 to 65507 octets Default: 100 octets	Specifies the size of the IP packet to be transmitted in a ping request executed by the source PE.
PingTimeout	1000 to 60000 milliseconds Default: 2000 milliseconds	Sets the amount of time for a source PE to wait for a ping response before the ping request times out.
PollingInterval	30 to 3600 seconds Default: 240 seconds	Sets the time between successive polls to retrieve the ping test results from the source PE.
PollingTimeout	2000 to 10000 milliseconds Default: 2000 milliseconds	Sets the amount of time to wait for a poll response before trying again to retrieve the ping test results from the source PE.
Retries	0 to 10 retries Default: 2	Sets the number of retry polls to perform when the initial poll fails.
SourceName	Regular expression Default: * (By default, all PEs are selected as source PEs.)	Specifies the wildcard expression to use to select the source PEs for PE-to-CE pings. An example entry is A*, which would limit the selected source PEs to just those that have names beginning with A.

For each PE-to-CE remote ping group configured by an administrator, MPLS Manager writes the ping entry to the source PE and periodically refreshes the ping entry in accordance to the “Refresh/calculation interval” on page 152, so that it does not expire until the administrator deliberately disables it.

Each configured PE-to-CE remote ping group is represented by MPLS Manager as a RemotePing object. The MPLS Management Suite User Guide describes the RemotePing object.
