VLAN configuration on 2510 and routing through Cisco 1841

[Shadow13]

Stacking in HP is not to combine the switch as 1 switch, it's only used to manage the switched through 1 IP address, but to configure them you need to configure each 1 seperatly

Hi Shadow,

Thanks for the reply.

The customer VLAN's are from 1 to 5 they dont want to change the VLAN number. So I thaought with stacking I will be able so see all the ports of the stack.

Anyway to do that.

[Shadow13]

configure the same vlans on the other switches and tagged the upling ports between the switches in these vlans except vlan 1 which should be untagged, then untag the ports of the clients in the vlan where you want to assign to them

Hi Shadow,

I tried and it did not work. Only the systems connected to the the first switch worked and were able to get the IP address from the the DHCP server which is configured on the router
The systems on the second and third switch were not getting connected please find below the configuration of the 3 switches and the router. The router is connected to the BB modem.
One other problem although the system on the first switch is getting the IP address but it is not able to reach the internet.

Please find the config of the three switches and the router.

Hi All,

REquest you help to go through the config and let me know what is wrong.
1.Why systems in the second and third switch not coming on the LAN
2.Allthough systems in the first switch was on the LAN they were not able to reach the internet.

Regards,
Eash

Hi all,

Any feed back on the configs

[eash]

Hi All,

Please help on the config.

Regards,
Eash.

[AndeasBehncke]

Hi eash,

1. Check your configuration of the native vlan, this need the components to "talk".
2. Did you can ping any System in the WAN or Internet? The default route on your Router shows an address, that i can not refer to your global IP configuration.

Hi andeas,

Thanks for the support.

The default route on the router is pointing to the customer's BB router and IP address on that device is 192.168.0.210. The present config on is the BB router is default gateway for the LAN and after the 2510 switch introduction the router sits between the 2510 and BB router.

Regarding your suggestion of native LAN it was not sure what you were referring to.

Regards,
Easwar.

the uplink ports between the switches should be untagged in VLAN 1 specially that the 1st switch uplink ports to the 2nd switch is untagged and on the 2nd switch they are tagged, this will lead to both switches not able to communicate to each other and of course the other switches also that connect through the 2nd switch will not be able to reach the 1st switch in VLAN 1

untag all the uplink ports in VLAN 1 plz
