Trick to remember 6500 troubleshooting order of commands .

HP-ELAW stands for Hari Prasada ELAM with wireshark.

1. H stands for Health check of the 6500 switch.
2. P  stands for programming check.
3. If both are correct , then do the ELAM,
4. If ELAM does not give any clue, do the wireshark packet capture.

Full description
------------------
1)
H for health checkups ---------- > RSP LIFE IN Q MIB 

R -- RP CPU status
S ---SP CPU  status

L -- logs on the switch
I ---Interface drops/Errors
F -- Fabric errors
E-- Earl or Forwarding  ASIC health


Q ----For QOS drops on switch.

M ---Memory issues on switch or TCAM limit
IB---- RP IBC and SP IBC drops.


2 ) P for switch programming  ------> SHAMMU IS RICH IN CA.

S---Spaning-tree status
H---HSRP status
A---ARP status
M--- Mac address learning
M--Mac move notification
U----Unicast flooding

RI -----RIB
C------ip cef programming
H- Hardware cef programming

C ---- Cef programming for ARP adjacency
H----- Hardware cef adjaceny programming.
 

OTV example on ASR1000

OTV COMMANDS on ASR1000

OTV running configuration

COMMON OTV MISCONFIGURATION


1. OTV adds extra overhead around 46 bytes which reduce the data throughput from default size of 1500 - 46= 1554.  Since OTV  sends all data packet with  DF-BIT set by default,  make  sure end to end MTU is working fine else OTV adjacency will not come up.

2. For Unicast mode, adjaceny-server needs to configure on the server side and use-adjacensy-server needs to configure on remote side which will register with Adjacency server.
