Vlan – Passing Vlans between HP Procurve and Dell Powerconnect switches

dellhp-procurvevlan

I have a core switch which is a HP Procurve switch with Vlans 1, 10, 20. I'm trying to setup an edge Dell switch. On the HP I have untagged vlan 1 and tagged vlans 10, 20 on port 1. On the Dell switch I changed port 16 to 'switchport general', with 10, 20 tagged (I think I had vlan 1 as the PVID). I then set port 2 as Switchport Access vlan 10.

When I connect a computer to port 2 on the Dell switch, it gets an IP from the vlan 1.

I haven't edited any encapsulation settings, so I assume they're both 802.1q, and I can't see any reference to encapsulation in the running config.

I have successful linked to HP Procurves before, I just haven't used a Dell switch before.

Any suggestions on what might be wrong?

I'm also a little confused about, when to use 'general' and when to use 'trunk' on the Dell switch.

Thanks.

Mode general and trunk are both used for VLAN trunking

mode general You may choose multiple tagged and untagged vlans, default is tagged

mode trunk You may define one native vlan, all others are tagged

mode access You may define a single untagged VLAN

Could you post your configuration for further troubleshooting? If you set the interface to mode access and specified the VLAN there should be no issue.

Routing – Dell PowerConnect 5524 VLAN routing

When testing networking connections, don't use windows machines.

My firewall was set to allow ICMP traffic from any subnet on any domain profile yet it was still blocking the packets.

Turning the firewall off completely allowed the traffic through, so the routing is working.

Also, pings probably aren't the best way to test network connectivity.

For anyone looking to route between two VLANs on the Dell PowerConnect 5524, the commands on page 220 of the user guide are sufficient:

en
config

vlan database
vlan 100-101
exit

interface gi1/0/1
switchport access vlan 100
ip address 1.1.1.1 255.255.255.0
exit

interface gi1/0/2
switchport access vlan 101
ip address 2.1.1.1 255.255.255.0
exit

Vlan – Setting up PIM Sparse mode

My questions are:

Should we setup on our core network switch OSPF with a router ID of 1.1.1.1 and then not set any OSPF settings on any other switch?

OSPF is not necessary for this implementation.

Would PIM Sparse Mode only need to be enabled on the core switches or on all of the switches in the network?

Pim-SM needs to be enabled on each L3 interface on which you want to allow the multicast traffic. For example, if you wish to contain the traffic to Vlans 15 and 14, you would have to do the following on your core:

configure
ip multicast
ip igmp
ip pim sparse
interface vlan 14
ip igmp
ip pim
interface vlan 15
ip igmp
ip pim
exit

If you want the traffic to traverse all Vlans, then you will need the appropriate interface configuration under each Vlan. Your L2 switches will need IGMP snooping turned on (ideally on all interfaces via the global configuration).

configure
ip igmp snooping 
bridge multicast filtering

For a very basic multicast setup like this, these should be the only features that you would need.
