I'm reading that my 5510, which has the Security Plus License, should have 2 interfaces capable of gigabit speed, but when I look at my ASA's interface's hardware properties in the gui, they are only capable of 100mb. When I look at them from the cli, they indicate a BW of 1000MB, but the speed auto negotiated with a 3820's gigabit interface, which is also set to auto, is only 100mb. However, I do notice the BW is set to 100000 on the 3820. Could that be what's preventing the gig interfaces from negotiating gig speed?
Interface Ethernet0/0 "outside", is up, line protocol is up
Hardware is i82546GB rev03, BW 1000 Mbps, DLY 10 usec
Auto-Duplex(Full-duplex), Auto-Speed(100 Mbps)
I'm looking to give a customer, who is currently terminated in a DMZ interface gigabit speed and was wondering if I could just rename either the inside or outside interface so it could swap with the current DMZ interface. Is it possible to just rename eth 0/0, or is there a hard rule that 0/0 must be the outside and e 0/1 must be the inside? And can anyone verify that the 5510 is in fact capable of having gig interfaces? I'm running 8.0(3)
The model should support it. What do you see if you do a "sh ver"? Also, there's not set rule that a certain interface be the outside, but I need to warn you. If you have any static nat, routes, anything that references the inside or outside interface and you swap them, the configs will change. Make a good backup of your config before changing the names with the nameif command.
You may want to try to hard set the interface on the switch and the ASA to see if it will connect correctly.
I couldn't see anything in sh ver that might have helped. I'll try hardcoding the speed and change the bw on my router to 1 gb and see what happens. Thanks for the feedback on the renaming of the interfaces.
