I have a 6506-E with a new SUP720. The switch has a 48 port Gig Ethernet SFP to support a large number of 3750 switches. The uplink is connected to a Cisco ASA 5550 configured to transparent mode.
The SUP720 has the following IOS: s72033-ipservicesk9_wan-mz.122-33.SXI2a.bin
The sup is a SUP720-3B and it does't have 10Gb connectios.
I am connecting to the firewall through Single Mode Fiber. I am using single mode SFP.
At this time my configuration only has the essentials: switchport configurations, IP address, default gateway, and a default route.
Here is my problem.
I tried connecting to the firewall with one of the ports of the SUP720 and while it shows good link, I can't reach the firewall or anything pass it. When I setup a port from the 48 port module, the same problem happens.
If I use an older IOS: s72033-pk9sv-mz.122-17d.SXB11a.bin
I can connect to the firewall and get pass it using an uplink on the 48 port module but not using the SUP720 ports.
I have no problems connecting to the 3750 via multimode fiber with either IOS.
The goal is to connect the uplink to the firewall using one of the ports from the SUP720.
