Output Field	Description
IP Address	The IP address.
State	Indicates the session state. The session state can be one of the following states: SHUTDOWN: Peer has been disabled.

Keep Alive Time	The keep alive timer (in seconds).
Hold Time	The hold time, which specifies how many seconds to wait for a keepalive or SA update message from a peer before closing the connection with the peer.
Age	The amount of time (in seconds) elapsed since the last keepalive or SA update message was received from a peer.
Message Sent	The number of messages sent. Statistics are shown for the following message types: Keep Alive Notifications Source-Active
Message Received	The number of messages received. Statistics are shown for the following message types: Keep Alive Notifications Source-Active
Lack of Resource	The number of messages from the peer that are dropped due to a lack of resources.
Last Connection Reset Reason	The reason the previous session was terminated.
Notification Message Error Code Received	Indicates if a notification message containing an error code was received.
Notification Message Error SubCode Received	Indicates if a notification message containing an error subcode was received.
Notification Message Error Code Transmitted	Indicates if a notification message containing an error code was sent.
Notification Message Error SubCode Transmitted	Indicates if a notification message containing an error subcode was sent.
Local IP Address	The local IPv4 address.
AO Keychain name:	The name of the TCP authentication keychain applied to the MSDP peer
TCP Connection state	The state of the connection.
TCP Keychain (name) details	Name and configuration details for applied TCP (AO) keychain.

	Send-id: Numeric identifier of send key
	Recv-id : Numeric identifier of expected receive key
	Include-tcp-options: YES/NO
	Accept-ao-mismatch: YES/NO
Recv-active-key	Configuration details for TCP key used to authenticate received TCP segments
	Crypto Algorithm : Name of key-exchange method used
	Send-id: Numeric identifier of send key
	Recv-id : Numeric identifier of expected receive key
	Include-tcp-options: YES/NO
Local host	The IP address of the device.
Local Port	The TCP port the device is using for the TCP session.
Remote host	The IP address of the neighbor.
Remote Port	The TCP port the neighbor is using for the TCP session.
SentSeq	The initial send sequence number for the session.
SendNext	The next sequence number to be sent.
TotUnAck	The number of sequence numbers sent by the device that have not been acknowledged by the neighbor.
SendWnd	The size of the send window.
TotSent	The number of sequence numbers sent to the neighbor.
ReTrans	The number of sequence numbers that the device retransmitted because they were not acknowledged.
IRcvSeq	The initial receive sequence number for the session.
RcvNext	The next sequence number expected from the neighbor.
RcvWnd	The size of the receive window.
TotalRcv	The number of sequence numbers received from the neighbor.
RcvQue	The number of sequence numbers in the receive queue.
SendQue	The number of sequence numbers in the send queue.
Input SA Filter	Indicates whether a filter has been applied for incoming SA messages from the peer.
Input (S,G) route-map	The route map configured to filter incoming SA messages from the peer for specific sources (S) and groups (G).
Input RP route-map	The route map configured to filter incoming SA messages from the peer for a specific rendezvous point (RP).
Output SA Filter	Indicates whether a filter has been applied for outgoing SA messages to the peer.
Output (S,G) route-map	The route map configured to filter outgoing SA messages to a peer for specific sources (S) and groups (G) .
Output RP route-map	The route map configured to filter outgoing SA messages to a peer for a specific RP.
SA message Drops	Number of SA messages dropped.
Bad_length	Number of SA messages dropped due to invalid length.
Invalid_VrfIdx	Number of SA messages dropped due to invalid VRF index.
Rpf_Failure_Drop	Number of SA messages that failed RPF check.
Wrong_group_Drop	Number of SA messages received for IPv4 multicast group address in the Local Network Control Block (224.0.0.0 – 224.0.0.255) or in the Internetwork Control Block (224.0.1.0 – 224.0.1.255). SA messages for these multicast group addresses will be dropped because the traffic to these group addresses is not routable.
Inbound_sg_Drop	Number of SA messages denied by the inbound SG filter for the peer.
Inbound_rp_Drop	Number of SA messages denied by the inbound RP filter for the peer.
Outbound_sg_Drop	Number of SA messages denied by the outbound SG filter for the peer.
Outbound_rp_Drop	Number of SA messages denied by the outbound RP filter for the peer.
