The SC0 port isn't relevant if you are using trunking to connect two switches. All you have to do is "SET TRUNK mod/port ON" on both switches and you are done. If you are talking about routing between VLAN's then you need an RSM or a router that is capable of ISL routing (2621 or better).

Re: ISL Trunking from a h/w's perspective [7:39246]
The only time the SC0 interface comes into play is for telnet into the box. If you have any 100 MB ports on your switch, you can run trunking. set trunk (mod/port) on isl If this trunk is running into a router, you need to create the subinterfaces on the router to enable routing between VLANS. int fa1/0.100 ip address (the subnet of the vlan) encap isl (the vlan #) HTH, Scott ""George Siaw"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > Do I need an Sc0 port when routing between Vlans?

Re: ISL Trunking from a h/w's perspective [7:39246]
The router's ethernet must be 100 full dux. You configure subinterfaces on the ethernet. a trunking protocol must be configured on each sub with the corresponding vlan #. The router will route between Vlans. Hope this helps.

RE: ISL Trunking from a h/w's perspective [7:39246]
Yes, you need to set up the ethernet for 2 sub-interfaces and set the encapsulation to isl and the isl id # to the vlan # you set up on the switch. if the router config is correct the router will route the vlans across the sub-interfaces on the router.

I don't know what else you want me to do to prove it. This was true at one time but it has changed. I have personally not tried this config and seen it work but if I have some time on Monday I'll confirm whether or not the 3660 will do as advertised.

RE: ISL Trunking from a h/w's perspective [7:39246]
Danny, Sometimes even people who work for Cisco, even SE's who may by CCIE's, make mistakes. The router never lies: 3620(config)#int ethernet 0/0.1 3620(config-subif)#encap ? dot1Q IEEE 802.1Q Virtual LAN sdeIEEE 802.10 Virtual LAN - Secure Data Exchange Notice this is an Ethernet, not FastEthernet, and that it does indeed allow 802.1q trunking. ISL, on the other hand, does require FastEthernet. So maybe that is where the confusion lies.

Yes, you can. You can setup 802.1q trunks on a 10mb interface just as Dave described. The information you received from Cisco pertains to ISL trunks, which require a 100mb interface.

When I took my switching course, three years ago, they were quite adamant that trunking could not be done on a 10 mb interface. Of course, that was before dot1q was available on the routers. If someone took their courses a while back then they probably aren't aware of the changes.

RE: ISL Trunking from a h/w's perspective [7:39246]
Answer #1 Sc0 is a virtual port. Think of it as a mini-PC in your switch that provides an address for management functions such as telnet. If you have physical access to your switch then the console port is the easiest way to configure your switch. If Sc0 is configured on the switch and you can connect to a link or port connected to the switch then you can telnet to the switch to configure it. Answer #2 If your question is really something like "I have a Cat5K with a Sup III blade that does not have any interface module - how do I configure trunking to this switch?" It depends on what other ports exist on the switch. Do a "show port capabilities" for each module. It will show if the module can be used for ISL trunking. Side note: Sup III interface modules come up on eBay from time to time. > -Original Message- > From: George Siaw [mailto:[EMAIL PROTECTED]] > Sent: Friday, March 22, 2002 5:45 PM > To: [EMAIL PROTECTED] > Subject: ISL Trunking from a h/w's perspective [7:39246] > > > Guys, > > > > Any ideas as how I can configure isl trunking without an Sc0 > port on the > supervisor engines?

"Danny Andaluz, CCNP" - It will work. did it on a 2611. Ci$co, won't support it and obviously they want you to buy more expensive 100 Mbps ports/routers (even if my total of 4 vlans uses 1mbps) Why do you believe everything cisco tells you ?
