IPSEC

Basic FCIP setup:
(14+2 card)
interface GigabitEthernet9/2
no shutdown
ip address 10.10.10.2 255.255.255.0
fcip profile 1
ip address 10.10.10.2
interface fcip1
no shutdown
no channel-group auto
use-profile 1
peer-info ipaddr 10.10.10.1

On 9216i:
interface fcip1
no shutdown
use-profile 1
peer-info ipaddr 10.10.10.2
fcip profile 1
ip address 10.10.10.1
interface GigabitEthernet1/16 (1/2 in newer code)
ip address 10.10.10.1 255.255.255.0
no shutdown

iZone merge failed

Looked zone on vsan 1 in 9509A:
MDS9509-B1# show zoneset active v 1
zoneset name zs1 vsan 1
zone name zone1 vsan 1
attribute qos priority high
pwwn 10:10:10:10:10:10:10:10

zone name test2 vsan 1
interface fc1/3 swwn 20:00:00:05:30:00:24:1e

zone name chip vsan 1
interface fc1/2 swwn 20:00:00:05:30:00:24:1e
interface fc1/5 swwn 20:00:00:05:30:00:24:1e

So enable qos on 9216i and reshut/no shut fcip1 and
zones merged fine.

StepII security:

MDS9509-B1(config-(crypto-map-ip))# set peer 10.10.10.1

MDS9509-B1(config)# interface gigabitethernet 9/2
MDS9509-B1(config-if)# crypto map domain ipsec cm1


Did same on 9216i except that peer 10.10.10.2 applied to interface gi 1/16 ( newer
SANOS code treats same interface gige 1/2)

------
upgrading to same version
--

after the upgrade 9216i gige interface became gigethernet 1/2 instead
of gig 1/16. Eventhough 10.10.10.1 was not in running config, if I try to
give gig 1/2 10.10.10.1 , it failed saying that config was already given.

So I did write erase and recopied config to running config. copy r s.

then applied crypto and ip to gig 1/2.
