Hi,
We have a vlan 10 - 192.168.5.1 /24 ( Static IP subnet ) on the core switch.
One pc is connected to a port (fa1/0/11) on an edge switch-ES01 ( which has this vlan 6 ) & assigned to vlan 6
Pc is given the ip 192.168.5.25 & gateway as 192.168.5.1
But, the pc is unable to ping the gateway. We tried with different laptop & also changed the fa1/0/11 interface to manual speed.
The configurations are as below:
On edge switch-ES01 where PC is connected ,
Int fa1/0/11
switch access vlan 6
desc test
On edge switch-ES01 port which uplinks to core ,
interface GigabitEthernet2/0/1
des Uplink to Core switch
switchport trunk encapsulation dot1q
switchport mode trunk
ip arp inspection trust
srr-queue bandwidth share 10 10 60 20
srr-queue bandwidth shape 10 0 0 0
queue-set 2
priority-queue out
mls qos trust cos
auto qos voip trust
channel-group 12 mode active
ip dhcp snooping trust
end
ip dhcp snooping vlan 1-999 is enabled on this edge switch
ip arp inspection is enabled for this vlan 6 in this edge switch
-----------------------------------
On Core Switch port connecting port to above edge switch:
interface GigabitEthernet2/3
switchport
switchport trunk encapsulation dot1q
switchport mode trunk
no ip address
wrr-queue bandwidth 5 25 70
wrr-queue queue-limit 5 25 40
wrr-queue random-detect min-threshold 1 80 100
wrr-queue random-detect min-threshold 2 100 10
wrr-queue random-detect min-threshold 3 50 60
wrr-queue random-detect max-threshold 1 100 10
wrr-queue random-detect max-threshold 2 100 10
wrr-queue random-detect max-threshold 3 60 70
wrr-queue cos-map 1 1 1
wrr-queue cos-map 2 1 0
wrr-queue cos-map 3 1 4 7
wrr-queue cos-map 3 2 2
wrr-queue cos-map 3 3 3
wrr-queue cos-map 3 4 6
mls qos trust cos
storm-control broadcast level 5.00
storm-control multicast level 5.00

Please help on this. thanks in advance.

Is there a typo in the above ie. you say it is vlan 10 on the core switch but vlan 6 on the other switch. It can't be both. If it is that is why you are not able to ping.

Hi,
I see that you have the laptop on vlan 6, and the gateway of that laptop is vlan 10 ip add 192.168.5.1/24 ?? Your gateway should be on the same vlan, you cannot have a laptop on vlan 6 and his gateway is vlan 10 there is no way this can ping its gateway since you they are on different vlans. You will need to have a SVI for vlan 6 on the core switch with a different subnet to achieve this.
What about if you put that laptop on vlan 10 an try again with the same ip on the laptop.

Sorry folks, it was a typo & was meant to be vlan 6 all the way.
I resolved it by removing arp inspection for this vlan .
Thanks for your help.
