# Monitoring IP

This section explains how to set a statistics baseline and use the show commands to view your IP configuration and monitor IP interfaces and statistics.

## System Event Logs

To troubleshoot and monitor IP, use the following system event logs:

- ipAccessList—IP access list matching
- ipEngine—IP chassis manager
- ipGeneral— IP general information
- ipIfCreator—IP interface creator events
- ipInterface—IP interface events
- ipNhopTrackerGeneral—Next-hop tracker for IP shared interfaces
- ipProfileMgr—IP profile manager events
- ipRoutePolicy— IP routing policy events
- ipRouteTable—IP routing table events
- ipTraffic—IP frame transmit and receive events
- ipTunnel—IP tunnel events

For more information about using event logs, see the JUNOSe System Event Logging Reference Guide.

## Establishing a Baseline

IP statistics are stored in system counters. The only way to reset the system counters is to reboot the router. You can, however, establish a baseline for IP statistics by setting a group of reference counters to zero.

baseline ip

- Use to set a statistics baseline for IP statistics. Baselining is not supported for IP socket statistics.
- The router implements the baseline by reading and storing the statistics at the time the baseline is set and then subtracting this baseline whenever baseline-relative statistics are retrieved.
- Use the delta keyword with IP show commands to specify that baselined statistics are to be shown.
- Example
  `
  host1#baseline ip
  `
- There is no no version.
- See baseline ip

baseline ip udp

- Use to set a statistics baseline for UDP statistics.
- The router implements the baseline by reading and storing the statistics at the time the baseline is set and then subtracting this baseline whenever baseline-relative statistics are retrieved.
- Use the delta keyword with IP show commands to specify that baselined statistics are to be shown.
- Example
  `
  host1#baseline ip udp
  `
- There is no no version.
- See baseline ip udp

baseline tcp

- Use to set a statistics baseline for all (both IPv4 and IPv6) TCP statistics or for only IPv4 or IPv6 statistics.
- The router implements the baseline by reading and storing the statistics at the time the baseline is set and then subtracting this baseline whenever baseline-relative statistics are retrieved.
- Use the ip keyword to implement a baseline for only IPv4 statistics.
- Use the delta keyword with IP show commands to specify that baselined statistics are to be shown.
- Example 1
  `
  host1#baseline tcp
  `
- Example 2
  `
  host1#baseline ip tcp
  `
- There is no no version.
- See baseline tcp

## IP show Commands

You can monitor the following aspects of IP using show ip commands:

To Display | Command
--- | ---
Access lists | show access-list show ip as-path-access-list
ARP | show arp
General IP information | show ip
IP addresses | show ip address
Community lists | show ip community-list
Routing table | show ip forwarding-table slot show forwarding-table route-holddown in JUNOSe Command Reference Guide
Interfaces | show ip interface
Shared IP interfaces | show ip interface shares
Protocols | show ip protocols
Redistribution policies | show ip redistribute
Routes | show ip route
Interfaces and next hops | show ip route slot
Socket statistics | show ip socket statistics
Static routes | show ip static
TCP ACK, RST, and SYN protection status | show tcp ack-rst-and-syn
Black hole threshold information | show tcp path-mtu-discovery
TCP statistics | show tcp statistics
Traffic | show ip traffic
UDP statistics | show ip udp statistics
Profiles | show ip profile
Route maps | show route-map

To set a statistics baseline for IP interfaces, use the baseline tcp and baseline ip udp commands. Use the delta keyword with IP show commands to specify that baselined statistics are to be shown.

You can use the output filtering feature of the show command to include or exclude lines of output based on a text string that you specify. See JUNOSe System Basics Configuration Guide, for details.

If you are losing packets because of fabric congestion, you can use the In Fabric Dropped Packets and Out Fabric Dropped Packets statistics to help determine the location of the bottleneck. Both statistics count the same thing—the same packets dropped because of fabric congestion—but in different directions.

At any given time, the total number of packets dropped in the fabric for all interfaces in the chassis is equal to the sum of all In Fabric Dropped Packets for all interfaces in the chassis, which equals the sum of all Out Fabric Dropped Packets for all interfaces in the chassis.

Packets not dropped for another listed reason are considered to have been dropped in the fabric. The router calculates In Fabric Dropped Packets by subtracting the total number of inbound packets dropped for all other reasons from the In Total Dropped Packets number. The router calculates Out Fabric Dropped Packets by subtracting the total number of outbound packets dropped for all other reasons from the Out Total Dropped Packets number.

The router calculates In Total Dropped Packets by subtracting In Forwarded Packets from In Received Packets. The router calculates Out Total Dropped Packets by subtracting Out Forwarded Packets from Out Received Packets. These statistics are reported while traffic is moving through the router. The router can get false statistics based on packets being forwarded or received after polling and based on which of the statistics is reported first. For example, In Forwarded Packets can be reported as greater than In Received Packets. Rather than displaying In Total Dropped Packets as a negative value, the command displays it as the sum of all drop reasons other than fabric drops; fabric drops are reported as 0, but might actually be nonzero. If you halt traffic, the In Total Dropped Packets and Out Total Dropped Packets values are always correct.

    - # ICMP TooBigs for unk. connection—Number of ICMP Too Big messages that the router has received for TCP connections that do not exist. When PMTU is disabled, this counter does not increase.
    - PMTU Increase Attempts—Number of attempts the router has made to increase the PMTU
    - Black Hole Detect Threshold—Number of successive transmissions that must occur on a connection before that connection treats retransmissions as indications that something is wrong
    - Override MSS—MSS that is advertised to peers, overriding the MSS that is derived from the interface MTU. This line does not appear in the output if you do not set the value.
  - MTU/MSS information—Information regarding path MTU/MSS
    - PMTU—Status of MTU/MSS on this virtual router: enabled or disabled
    - MSS in effect—MSS currently being used for transmission to the peer. This number changes while various network events occur to cause the router to increase or decrease its estimate of the MSS.
    - Calculated MSS to peer—MSS that path MTU discovery has calculated (if PMTUD is enabled) to the peer
    - MSS received from peer—MSS that the peer received in a TCP MSS option. If no option is received, the value is zero (0).
    - Application set MSS—MSS that an application might have set for the connection

    - Time to next increase attempt—Amount of time, in seconds, until the router retries to increase the MTU
    - Black Hole Detection State—State of the black hole detection mechanism: none, detecting, probable, or unknown
  - Out-of-Order Packet Queue Information—Information regarding packet queue buffers
    - Buffers Outstanding—Number of buffers currently on the connection reordering queue
    - High Water—Most buffers that have ever been on the connection reordering queue
    - Buffers discarded—Number of buffers that were discarded because keeping them would have exceeded the connection maximum
  - TCP PAWS is [enabled/disabled]—Status of the TCP PAWS option; enabled indicates that PAWS is functioning normally (default mode) for TCP segments; disabled indicates that PAWS is disabled for TCP segments
