show ppp statistics
Syntax
Release Information
Command introduced in Junos OS Release 7.5.
Description
Display PPP interface statistics information.
Options
detail | — | (Optional) Display the detailed statistics. |
memory | — | (Optional) Display PPP process memory statistics. |
recovery | — | (Optional) Display recovery state of PPP after a GRES or restart. It is safe to force another GRES or restart only when the recovery state indicates the recovery is done.

Output Fields
Table 1 lists the output fields for the show ppp statistics command. Output fields are listed in the approximate order in which they appear.
Table 1: show ppp statistics Output Fields
Field Name | Field Description | Level of Output |
|---|---|---|
Total sessions | Number of PPP sessions on an interface. | none detail |
Sessions in disabled phase | Number of PPP sessions disabled. Number of sessions where the link is either administratively or physically down. Once the PPP process learns from the kernel that Layer 2 is ready to send and receive traffic, it will do a phase transition from disabled to established. When LCP and NCP transitions through states, links transition to the establish phase when terminate packets are exchanged or some other failure, such as authentication or expiration of a timer occurs. | none detail |
Sessions in establish phase | Number of PPP sessions in establish phase. In order to establish communications over a point-to-point link, each end of the PPP link must first send LCP packets to configure and test the data link. | none detail |
Sessions in authenticate phase | Number of PPP sessions in authenticate phase. Each end of the PPP link must first send LCP packets to configure the data link during the link establishment phase. After the link has been established, PPP provides for an optional authentication phase before proceeding to the Network-Layer Protocol (NLP) phase. | none detail |
Sessions in network phase | Number of PPP sessions in the network phase. After a link has been established and optional facilities have been negotiated as needed by the LCP, PPP must send Network Control Protocol (NCP) packets to choose and configure one or more network-layer protocols, such as IP, IPX, or AppleTalk. Once each of the chosen network-layer protocols has been configured, datagrams from each network-layer protocol can be sent over the link. | none detail |
Bundles in pending phase | Number of unique bundles to which PPP links are referring. | none detail |
Type | Type of structure for which memory is allocated.
| detail |
Type (continued) |
| detail |
Type | If you specify the memory keyword, the following memory statistics are displayed for Ethernet interfaces on M120 and M320 routers.
| memory |
Total | Total memory allocations. | detail |
Size | Size of the structure. | detail |
Active | Number of instances of the structure that are used. | detail |
Free | Number of instances of the structure that are on the free list. Types with a number in the Free column are pooled structures, and are typically types that are often used. | detail |
Limit | Maximum number of instances that can be on the free list. Types with a number in the Limit column are pooled structures, and are typically types that are often used. | detail |
Total size | Total amount of memory being used by a type of structure (includes active and free instances). | detail |
Requests | Number of allocation requests made by a type of structure. | detail |
Failures | Number of failed allocations. | detail |
Recovery state | State of PPP recovery after a GRES or restart:
| none |
Subscriber sessions pending retention | Number of PPP subscriber sessions that are in the process of being recovered. | none |
Subscriber sessions recovered OK | Number of PPP subscriber sessions that have recovered after a GRES or restart. | none |
Subscriber sessions recovery failed | Number of PPP subscriber sessions that have failed to recover after a GRES or restart. | none |
