I have a set of 3 cisco 1900s switches all uplinked to cisco 2900XL which is uplinked to a MT RB532, and then the internet…all works great all the time.. i just have everyone plugged into the 1900s on the same 192.168.5.0/24 network via DHCP addresses.
I want to isolate all broadcast traffic to each port (idealy) or to each switch (if more reliable).
I was thinking per port VLANs or per switch VLANs…or if more, smaller subnets for just IP traffic.. but im not really sure.
looks like your are right..and it turns out the 2900 sw i have (2916xl-m16) has the 4mb flash so it does not support the REQUIRED ios update to do any kind of vlans…which is why i love mt stuff.
Question:
anyway, does anyone know of a way to do isl to 802.1q other than the 2900s? i guess what im asking is are there any other cheap siwtches or something i can do in mt to make this happen.?
the point is it would be SO great be able to use a few of the ~30$ 24 pt cisco 1900 switches with an MT or 2 boxes running the show..i have so many installs that this would be great for…users dont need more than a full duplex 10mbit for internet lines…
3com/ibm make an excellent 100mb managed switch that has vlans - I’ve bought about 5 from Ebay over the past year at < $50 each. I even got one at $29. They are enterprise class switches (4m/pps), but since they are only 100mb they are getting cheap.
i was paying ~35-40 for 24pt cisco 1900 10mbit duplex.. not 802.1q
i question though: it seems to say for trunking of the vlans (uplinks) you need to use GVRP or the propritary 3com stuff.. does mt support that, ie have you uplinked vlans from the 3com switch to a MT box?
Yes, it supports both their proprietary trunking as well as standard 802.1q tagging. I have 10-12 vlans with MT on each and they work great.
This switch is the only one that will give you SNMP counts for each vlan independently as well - I have searched the earth and there are no other switches that will do this - other than a high end cisco.
