Symptoms

Management traffic (SSH and SNMP) stopped working after upgrade from 6.x to 7.x.

Cause

The upgrade from vxworks-based images (6.x release) to linux-based images (7.x release) requires attention to default-gateway and host route configuration.

Solution

After migration to Linux we actually honor the gateways set for each interface more strictly. So the route tables have a gateway for each media interface. The default-gateway applies to the management interfaces (i.e. - wancom0) beyond 7.2.

So customers should update their config to have same default-gateway as per the wancom0 subnet.

Here is an example from one of our lab -

3800-2(configure)# bootparam

'.' = clear field; '-' = go to previous field; q = quit

boot device : eth0
processor number : 0
host name : abcd.xyz
file name : /code/images/nnECZ730m2p1.32.bz
inet on ethernet (e) : aa.bb.cc.dd:ffffff00
inet on backplane (b) :
host inet (h) : xx.yy.zz.xx
gateway inet (g) : aa.bb.cc.1 -------------------------> This will be same as default-gateway
user (u) : vxftp
ftp password (pw) (blank = use rsh) : vxftp
flags (f) : 0x8
target name (tn) : sbc-lab
startup script (s) :
other (o) :

3800-2# show running-config system-config
system-config

comm-monitor
state disabled
sbc-grp-id 0
tls-profile
qos-enable enabled
call-trace disabled
internal-trace disabled
log-filter all
default-gateway aa.bb.cc.1 -----------------> This will be same as gateway of management interface or wancom0
restart enabled

Note :- This is applicable to SCZ versions also as the vxworks to linux migration was done for both ECZ and SCZ version .
