Suggestions for BCMSN lab? |
|
|
I'm putting together a BCMSN lab for myself. I've only barely begun
studying, and VLAN was my weakest subject in CCNA, so I'm unsure what
hardware I need to proceed.
So far I've got a whole stack of 2500s, and a 1912 in the mail, but as
I understand it I need at least a 2600 for the inter-VLAN routing. (Or
I could use a 3550 to do L3 switching? But finding a cheap used 3550
doesn't seem realistic yet.)
Will the 1912 suffice to do the trunking? The Lammle CCNA quotes
configurations for a 1900 doing ISL, on a FA uplink port. That same
Lammle also refers to 2950 configs, but what about a 2912 / 2924? I
have been making use of www.expert-labs.com and there's a 2924XL in the
pod I've used, but "switchport mode trunk" is an invalid command. (The
IOS may be too old?)
In short - which switch(es) can I use to uplink to a router for
inter-VLAN? (I'd like to practice with more than just one.)
Now, on to the router. I don't want to assume anything, so I'll just
ask: can a 2500 support VLANs?
Or what about a 2610 without any fast ethernet ports? There's one of
those in the expert-labs pod, and all of the trunk / VTP commands work
on e0/0, yet the Lammle had told me a FE interface would be required.
Finally, what IOS at a minimum should I be running to practice for the
current BCMSN? Will 12.0 suffice?
Thanks for any suggestions and comments! |

This is a guess.
I think that you need a Fe port for trunking
of any kind, was never put into the 10M ports.
The place to look was the release notes. I would guess that
now a lot if this in in the Feature NAvigator.
What you need to do is to scour the release notes and
product brochures for the features that you need.
Assume that the material has NO negatives in it.
That is it will NEVER say - By the way
unllike all of the other models this one does not
support xyz. It is a one way street. With things like the
old ......XL switches it can be very hard to figure out exactly
what is supported and what is not.
I worked with all of this every day about 5 years ago
and it was sometimes really tough to supply stuff that
worked. I recall opening TAC cases to determine if model XX
did ISL or not, and then getting the wrong answer.
I seem to recall that with the 29....[xl] ([optional])
The models changed very fast with the exact same model
number being used for different hardware.
IIRC 2900xl is NOT at all the same as 2900.
Good luck. One thing is that they are cheaper now:)) |

2610's (10Mbs only routers) can do trunking depending on the IOS. I've
done it personally and posted the prerequisites before.

Good to have you back.
Thanks for that. The 10M no trunk rule was one that
seemed I think to work for me for a bit.
However, what can you connect it to? Good for lab I guess. |

Thanks for the answers so far, everyone.
I think I found the answer to one particular question, too. Richard
Deal states in his BCMSN,
"802.1Q and ISL are supported on the routers, but ISL is supported only
on Fast Ethernet or faster ports."
I'm not as concerned with ISL, as Cisco is phasing it out. Also, from
my limited understanding, once you've picked the one or the other, the
configuration is largely the same, so the difference is really in just
the encapsulation command itself.
I'm still trying to determine if a 2900XL will support trunking with a
recent IOS. I know a 2950 will, but those are still relatively
expensive on eBay.
I'm also still trying to determine the cheapest router I can use for
the inter-VLAN. (I'll be using router on a stick, unless I find some
really good deal on a 3550.) Or I suppose I could hunt down a 2514... |

I'm almost positive 2900XLs could only do ISL and not dot1Q. The XL
models were a bit wacky becaus there it went through quite a few
transitions. As I recall, even the LED label/stamping colors made a
difference in the mdoel number!

No 2500's can do trunking. 2610 is the lowest model that will do
dot1q.

Lab is right. And some very low end use I suppose.

The 2900XLs will quite happily do dot1q - at least the 8MB models.

Greettings,

A 2900-xl (with reasonably current IOS) will support both ISL and
dot1q, whereas a 2950 only does dot1q. Its about the only thing a
2900-xl can do that a 2950 can't.............;-) The other annoying
thing about the 2900-xl is that the interface range command is not
accepted. Grrrrrrrr......;-(

Some of the fairly recent Ethernet (10Mb) versions of IOS on some
platforms can do trunking, but generally you need 100Mb to be able to
do trunking.

Again, thanks for the replies, everyone. Looks like I'll be bargain
hunting on a 2900XL and a 2610. The 2514 idea was to do inter-VLAN the
old-fashioned way; the 14 has two Ethernet interfaces. I think I could
do the setup for Ethernet routing in my head, though, so practice
wouldn't be as useful as with a trunk to a router. |
