What are these specific command under Global <subint,maplist,mapclass> 1

[ase2dais]

Going into Global conf mode in a 2500
router#conf t
router(conf)# ?
interface (that I know)
subinterface (nver run accross that)
Map-list (now what the hell is maplist)
Map-class ( anyone ever use that one)
Line (thats easy, used that before)
router (Done that before !)
IPX-router (some recollection is needed here)
Router-map ( any takers ?)

.. have someone run some of these commands before, subinterface, maplist,mapclass. ipx-router and route-map ?

... I am in a Cisco NetAcad and the instructor is limited on his knowledge, hoping someone may have some of the answer out ther!

thks in advance!

subinterface - used with various technologies (frame-relay, ATM, ethernet when trunking) to create logical interfaces on a single physical interface. Each logical interface is configured as a subinterface.

map-list - used with ATM to create a mapping of protocol to VPI/VCI pairing, along with setting additional parameters. This is actually an older command that isn't really used anymore, rather, you can just specify the vpi/vci on the interface, rather than having to call the map-list to the interface with the map-group command.

ipx router - this is to enable different ipx routing protocols. by default ipx RIP is enabled, even though it doesn't show it in the config when you do a show run. If you want to disable ipx RIP you have to turn it off with no ipx router rip. Other IPX routing protocols include IPX EIGRP and NLSP.

route-map - a route-map is used as a means to conditional set certain characteristics in certain situations. Using a match (the if portion, if you want to compare it to an if, then statement) command to specify what networks or packet types will be matched with a set (the then portion) command you can conditionally set attributes. Route-maps are mostly used with BGP to set attributes on incoming and outgoing updates, policy routing to set various IP precedence and next hop attributes, and when redistributing from one routing protocol to another. They are similar to access-lists but allow for more functionality.

Thks Eric!

Its amazing how a simple answer of one, unlocks the frustrating mystery of the other.

I guest I won't be using these commands anytime soon, I do have a question, while I have a CCIS on board. I understand this new 2600 IOS comes equiped with ssh for telneting.

I have TTSSH, (

http://www.zip.com.au/~roca/ttssh.html)and

is the one I am using, it just could not connect to the router. What CLI command would enable the router to accept ssh telnet connection. (Regular Telnet works!)

Any comments !

Well, the SSH support will replace Reverse Telnet. Reverse Telnet is used to connect to the console ports of other devices through the tty lines.

Basically a router can act as an access server having nunmerous TTY lines that connect to the console port of other devices. SSH can be used a replacement for reverse telnet. I do not think that it can be used to actually telnet directly to a device, but I may be mistaken on this.....i will research it and if I find anything I will let you know....
