show ip eigrp neighbor

[rkunta]

Hello there!

I am not able to find out the info related to the numbers under "H" column in output of sh ip eigrp nei command. I tried cisco command references but in vain. Could some one kindly help me understand?

Thank you...

The H column simply shows the order in which the EIGRP neigborships were established.

Hi, rkunta.

As Jon say the H value is the order as EIGRP neighboring is established.

Table 45     show ip eigrp neighbors Field Descriptions

Field	Description
process 77	Autonomous system number specified in the router configuration command.
H	This column lists the order in which a peering session was established  with the specified neighbor. The order is specified with sequential  numbering starting with 0.
Address	IP address of the EIGRP peer.
Interface	Interface on which the router is receiving hello packets from the peer.
Holdtime	Length of time (in seconds) that the Cisco IOS software will wait to  hear from the peer before declaring it down. If the peer is using the  default hold time, this number will be less than 15. If the peer  configures a nondefault hold time, the nondefault hold time will be  displayed.
Uptime	Elapsed time (in hours:minutes: seconds) since the local router first heard from this neighbor.
Q Count	Number of EIGRP packets (update, query, and reply) that the software is waiting to send.
Seq Num	Sequence number of the last update, query, or reply packet that was received from this neighbor.
SRTT	Smoothed round-trip time. This is the number of milliseconds required  for an EIGRP packet to be sent to this neighbor and for the local router  to receive an acknowledgment of that packet.
RTO	Retransmission timeout (in milliseconds). This is the amount of time the  software waits before resending a packet from the retransmission queue  to a neighbor.
Version	The software version that the specified peer is running.
Retrans	The number of times that a packet has been retransmitted.
Retries	The number of times an attempt was made to retransmit a packet.
Restart time	Elapsed time (in hours:minutes: seconds) since the specified neighbor has restarted.

I hope help you.

Hello Ram,

In addition to great Jon's and David's posts, the H letter in the first column supposedly stands for "Handle" - a number internally representing a particular EIGRP neighbor. The neighbors are numbered in sequential increasing order as they are detected.

Best regards,

Peter
