display msdp peer-status

Function

The display msdp peer-status command displays the detailed information about MSDP peers.

Format

display msdp [ vpn-instance vpn-instance-name | all-instance ] peer-status [ peer-address ]

Parameters

Parameter	Description	Value
vpn-instance vpn-instance-name	Specifies a VPN instance. vpn-instance-name specifies the name of the VPN instance.	The value must be an existing VPN instance name.
all-instance	Indicates all the instances. If vpn-instance or all-instance is not specified, only the public network instance is displayed.	-
peer-address	Specifies the address of a remote MSDP peer. If this parameter is not specified, information about all the MSDP peers in the instance is displayed.	The address is in dotted decimal notation.

Usage Guidelines

Usage Scenario

After MSDP peers establish a TCP connection, the display msdp peer-status command can be used to display the detailed information about a specified MSDP peer, such as the interface status, interface configuration, policy for filtering messages, and number of messages.

Precautions

This command displays the detailed information about a specified MSDP peer only when the MSDP peer has been configured.

Example

# Display the detailed information about the MSDP peer 10.110.11.11.

**Table 1** Description of the **display msdp peer-status** command output
Item	Description
MSDP Peer	Address of the peer. This parameter is configured using the peer connect-interface (MSDP) command.
AS	AS number of the MSDP peer. A question mark (?) indicates that the AS number cannot be obtained.
Description	Description of the verbose information.
Information about connection status	Information of connection status.
State	Status of the MSDP session. Up: The connection is set up and is in the Up state. Listen: The local device acts as the server. The connection is not set up. Connect: The local device acts as the client. The connection is not set up. Shutdown: The MSDP peer is in Shutdown state. Down: The connection fails.
Up/down time	Time when the session becomes Up or Down. The time format is as follows: Time that is shorter than or equal to 24 hours: hour: minute: second. Time that is longer than 24 hours but shorter than or equal to one week: day: hour. Time that is longer than one week: week: day.
Resets	Resetting times.
Connection interface	Address of a connect-interface that is used to set up the TCP connection with the peer address. This parameter is configured using the peer connect-interface (MSDP) command.
Number of sent/received messages	Number of MSDP messages received or sent through the connection.
Number of discarded output messages	Number of discarded messages.
Elapsed time since last connection or counters clear	Time that elapsed since the MSDP peer resetting count and control packet statistics were reset.
Information about (Source, Group)-based SA filtering policy	Import policy: is used to receive the filtering list of the SA messages of a specified MSDP peer. You can configure the policy using the peer sa-policy import command. Export policy: is used to forward the filtering list of the SA messages of a specified MSDP peer. You can configure the policy using the peer sa-policy export command. By default, the SA messages received and forwarded are not filtered. The MSDP peer receives and forwards all the SA messages. The item is expressed by none.
Information about SA-Requests	Policy to accept SA-Request messages: restricts the SA request messages received from an MSDP peer by the switch. By default, the switch receives all the SA Request messages sent by the MSDP peer. The item is expressed by none. You can set the policy using the peer sa-request-policy command. Sending SA-Requests status: enables or disables the switch to send SA request messages to a specified MSDP peer when the switch receives a Join message. By default, when receiving a Join message, the switch does not send the SA Request message to its MSDP peers, but waits for the next SA message. You can configure the switch to send SA Request messages using the peer request-sa-enable command.
Minimum TTL to forward SA with encapsulated data	If the SA message received is encapsulated with the multicast data packet, the switch forwards the SA message to other peers only when the TTL of the packet is not smaller than the minimum TTL. You can configure the function using the peer minimum-ttl command.
SAs learned from this peer	SA messages that pass through the MSDP peer and the number of SA entries in the cache.
SA-cache maximum for the peer	Maximum number of (S, G) entries in the cache when the switch receives the SA message from an MSDP peer. You can configure the maximum number of (S, G) entries in the cache using the peer sa-cache-maximum command.
Input queue size	Length of the data in the input cache.
Output queue size	Length of the data in the output cache.
Counters for MSDP message	Number of MSDP messages. Count of RPF check failure: indicates the number of SA messages discarded because of the RPF check failure. Incoming/outgoing SA messages: indicates the number of sent or received SA messages. Incoming/outgoing SA requests: indicates the number of sent or received SA-Request messages. Incoming/outgoing SA responses: indicates the number of sent or received SA-Response messages. Incoming/outgoing data packets: indicates the number of sent or received SA messages that are encapsulated with multicast data packets.
Peer authentication	Whether MSDP authentication is configured.
Peer authentication type	MSDP authentication modes, including: none: indicates authentication is not configured. MD5: indicates MD5 authentication. This parameter is configured using the peer password (MSDP) command. Keychain: indicates Keychain authentication. This parameter is configured using the peer keychain (MSDP) command.
