5524 vlan config with iSCSI and LAN
Hello all,
I can't get my iscsi working.
It is really frustrating. I can't get my vlan 168 working.
If I configure a inter switch connection I can not ping devices on the opposite switch. I have tried to use the trunk port as connection port and some other access port in vlan 168. There is no connection possible.
Is there something wrong with the config?
There is a Equallogic SAN behind the iSCSI and I read in the forum that you should not use flow control and iSCSI optimations.
can you please help me?
I attach both configuration files.
regards
Dennis

Here is a great article on Dell EqualLogic™ iSCSI Optimization for Dell PowerConnect ™ Switches
www.dell.com/.../Dell_EqualLogic_%20iSCSI_Optimization_for_Dell_Power_onnect_%20Switches.pdf
Have you had a chance to look at this whitepaper discussing iSCSI configuration.
en.community.dell.com/.../2586.powerconnect-55xx-iscsi-configuration.aspx
EqualLogic Configuration Guide
en.community.dell.com/.../2639.equallogic-configuration-guide.aspx
en.community.dell.com/.../3615.rapid-equallogic-configuration-portal-by-sis.aspx
I see in your text file that you have both access and trunk set on interface 1/0/23.
You can run the command to clear out the switchport mode on the interface.
PC5548P(config)# int te1/0/23
PC5548P(config-if)# no switchport mode
You may need to strip out the switchport mode with this command and start over with just the trunk mode. If you have a need to trunk and access you may consider a general switchport mode.
General Links consist of a combination of VLAN Trunk and Access Links. General Links can have both tagged and untagged frames, However, all frames sent to a specific VLAN must be tagged. All untagged frames are sent to the native VLAN. The native VLAN still applies to the General LINK. While it is possible to have multiple untagged vlans on a General link, you can only have ONE (1) PVID. The PVID represents the native VLAN. While untagged traffic may be sent via several untagged VLANs, returning untagged traffic will only be received by the PVID and therefore will NOT be forwarded to a specific VLAN.
Command example:
console# configure
console(config)# interface ethernet e11
console(config-if)# switchport mode general
console(config-if)# switchport general allowed vlan add 100 tagged
console(config-if)# switchport general allowed vlan add 1 untagged
console(config-if)# end
Hope this helps,
Keep us updated if you can.

Do I need diffenrent IDs on the switches? Or is on both switches ID 1 fine?

So I should use iSCSI optimazions and flow control?
And I just have to correct my switchport mode and i have a interconnect with my two switches?
I can't believe it.
I also tried to plug a cable between port 1/0/15 on both switches and there was also no communication between my vlans.

First of all, the 5524 is not a validated switch for use with the EqualLogic array, you can see this here:
http://en.community.dell.com/techcenter/storage/w/wiki/2661.equallogic-compatibility-matrix.aspx
This switch is for lower tier iSCSI devices, one of the reasons is that the memory buffers per port is not enough for iSCSI traffic generated with an enterprise class SAN like the PS Array.
With that said, you may be able to “get by” with one (or two) host servers and one array with this switch. Beyond that you should upgrade the switch.
The general setting are as follows:
- Turn Flow Control ON
- Turn Spanning Tree PORTFAST ON for each port in the iSCSI vlan (remember that the hosts and array ports need to be on this vlan, so
a separate dedicated iSCSI interface on each host is required)
- Turn Jumbo Frames ON (I highly recommend setting up the initial configuration without Jumbo frames (set it to disabled first), then after you establish the iSCSI connectiion you can try using jumbos. However be advised that since this is not an enterprise class switch, you may have issues using Jumbo.
- Turn iSCSI Optimization OFF
- Remove iscsi 0.0.0.0 targets in UI
