6248 connect to Cisco on VLAN
Hi,
I am trying to connect a 6248 to a Cisco router.
I can ping 10.0.10.254 from the Cisco side of the network but I can't ping 10.0.10.253.
I can ping 10.0.10.253 from the Dell side of the network but I can't ping 10.0.10.254.
The port on the cisco is configured like this witht two IP addresses:
!
interface FastEthernet0/1
description Internal LAN
ip address 192.168.9.254 255.255.255.0 secondary
ip address 192.168.1.254 255.255.255.0
no ip redirects
no ip unreachables
no ip proxy-arp
ip route-cache flow
duplex auto
speed auto
no cdp enable
!
interface FastEthernet0/1.10
description NEW LINK to switches
encapsulation dot1Q 10
ip address 10.0.10.254 255.255.255.248
no ip redirects
no ip unreachables
no ip proxy-arp
no cdp enable
!
ip route 10.0.0.0 255.255.0.0 10.0.10.253
The 6248 is configured like this:
interface vlan 10
name "Connection to Cisco"
routing
ip address 10.0.10.253 255.255.255.248
interface ethernet 3/g37
spanning-tree portfast
switchport mode general
no switchport general acceptable-frame-type tagged-only
switchport general allowed vlan add 101
switchport general allowed vlan add 10 tagged
exit

Here is the document I would use to help setup a LAG between your cisco and powerconnect.
www.dell.com/.../pwcnt_link_aggregation.pdf
www.dell.com/.../pwcnt_m6220_cisco.pdf
The documnent outlines the basics of getting a connection between the two devices. Once you have the devices connected and communicated, then you can proceed with any other configurations on that port.
Some things to make notes of:
The port speeds need to match on both sides.
It looks like on the cisco side you have a static route setup?
But on the powerconnect side there is no static route setup and switchport mode is general. Usually when connecting two VLAN aware devices together trunk mode is used.
It looks like you have portfast enabled on the port that connects the two devices.
Portfast is used for non-switch devices
• Clients
• Servers
• Printers
Let me know if this info does not help out, and I can do some more research into the subject.
Thanks.

OK, did some more research on this. And it looks like you can keep the portfast enabled on the port.
I said Trunk mode, but it turns out Access mode would be better suited.
Vlan 10 should only have the two router ports in it, and no other ports connected to anything else.
Then setup the static route on each end to allow traffic to flow.
On the Powerconnect it is the same kind of command.
ip route 10.0.0.0 255.255.0.0 10.0.10.254
You would need to do this for each VLAN that needed access to the other switch.
You could also try
Ip route 0.0.0.0 0.0.0.0 10.0.10.(253/254)
To encompass all traffic.
Let us know what your updated configuration looks like and if it works.

Thanks Daniel,
What is the syntax for adding a static route on the 6248 ?
Your help is greatly appreciated.

Still no luck. This is what the config looks like now. VLAN 10 is only on the port directly connected to the Cisco. Set the route as shown above. When I switch to Access mode on the port - all traffic stops - so i set it to General.

Lets try getting rid of the static route between the two, it may be causing issues in this case.
We could do something like this.
Powerconnect:
switchport mode general
switchport general allowed vlan add 10 tagged (Add required multiple vlan number which you want to pass thru this channel)
This would be for the cisco, and may change some based on your model. So I would double check. But this is the basic idea.
switch
switch trunk encap dot
switch mode trunk
switch trunk allowed vlan 100
end
Let us know how this changes things.
Thanks.
