can't ping ip on Interface vlan

[warmanovic]

hi All..

i have tried to add new IP MGMT to our switch..and the old IP MGMT still on the config

i have created vlan 9 for the new IP MGMT, and also add ip address on it:

interface Vlan9
 ip address 10.170.40.19 255.255.255.0
 no ip redirects
 no ip unreachables
 no ip proxy-arp
 ip flow ingress
 ip flow egress

and here are the old IP Management:

interface Vlan5
 ip address 128.236.96.239 255.255.255.0
 no ip redirects
 no ip unreachables
 no ip proxy-arp
 ip flow ingress
 ip flow egress

but until now, we can't ping or telnet to new IP MGMT from another sw/router...

is there any wrong with the config(please check attachments)?

there is no restriction from our Firewall to access that IP.

please help...

Thank you

hi,

do you have routing (static or dynamic) for 10.170.40.0/24?

try to add this:

no ip route 0.0.0.0 0.0.0.0 128.236.96.3
ip route 0.0.0.0 0.0.0.0 10.170.40.x

Hi John

is it ok right, if we put both " ip route 0.0.0.0 0.0.0.0 128.236.96.3" and "ip route 0.0.0.0 0.0.0.0 10.170.40.x" ?

hi,

no, the L3 switch will load balance between the two default route.

also make sure the design of your switch will do Layer 2 or Layer 3 (routing).

if it's only L2, the you just need the ip default-gateway 10.170.40.x command.

[warmanovic]

it will do layer 3

if i erase the ip route 0.0.0.0 0.0.0.0 128.236.96.3

and the command :

interface Vlan5
 ip address 128.236.96.239 255.255.255.0
 no ip redirects
 no ip unreachables
 no ip proxy-arp
 ip flow ingress
 ip flow egress

will not function anymore right?

because we can't ping 128.236.96.239?

please advise

yes, you might lose remote connection.

i would suggest to do it on a maintenance window.
