Cisco Switch, Talking with Dell Switch, using GBIC fiber
I have problem with our Cisco switches and our Dell switches using GBIC 1000baseSX modules(All Cisco brand GBIC's). I have one 3548xl, and one 3524xl, and Four Dell 3024 switches. The Cisco IOS is 12.0(5) WC7, the newest, and so is the Dells firmware. I have tried this from both 3548, and 3524, and neither work. Going from either Cisco 3548/24 switch to any of the Dell switches. Going from either of the two Cisco switches works, and between both Dell switches it works, BUT between the Cisco and Dell this does not, and the Dell shows the port is green, but the Cisco port does not have any lights.
This is the Config interface port on the 3524, Gi 0/1 goes to the Cisco 3548 GBIC, and the Gi 0/2 goes to the Dell GBIC. I have changed the Access Mode VLAN on the Gi 0/2 port, and this did not change. I have the GBIC working from the 3548 to the 3524, and between the two Dellss, BUT its getting them to talk from the Cisco 3524 to the Dell 3024. I have changes the encapsulation from isl to dot1q, this did not help. The dell GBIC port is set to 1000, FULL. Automatically, and can not be changed, I have played with the duplex and speed on the Cisco port but no luck! Turned off flow control on both ends, no luck!, Alos I have used different fiber cables, no luck!

If the Dell switches does support 802.1q tagging then you should try to manually configure the trunk mode on instead of auto. contact Dell and see whether there is a way to manually configure 801.q trunk on the Dell switch.

interface we use the VLAN tag to demultiplex the VLANs. The switch needs
to determine which MAC Address table to look in for a forwarding
decision. To do this we require the switch to do...
