Greetings, people!

The question is:

Is it possible to stack two or more SGE2000 sw in Layer 3 operation mode (so that they all act as a single router...)? 
Correct Answer by chrcoope about 7 years 7 months ago

I have never done so but yes. Put both units in layer three mode, then stack.

... And there are some more questions:

(1) Is there any limit on the number of "IP interfaces" one can setup for the SGE2000?...

(2) I've read that if one has some stackable gigabit switches, the link between them should be at least 10Gpps... but the model has only 1Gbit interconnection between nodes? May this bring any performance issues with the stack?

(3) Does it have a  'dedicated stacking bandwidth"?

(4) (The question has being answered, just wanted to put it in the checklist for somebody to confirm it one more time) Layer 3 redundancy: is it offered with the SGE2000 stacking technology?

(5) Are issues with working with the web interface from firefox web browser completely resolved in the latest firmware? (so that we will not be forced to use IE software to configure the sw)?

It's strange, but in the documenttion a have read the following:


IMPORTANT: If the Ethernet switch is
being used as part of a Linksys One
system, it must operate as a Layer 2


What's this suppose to mean?... hmm....

Now for a little bit of history to explain that warning.

The   Linksys One Services Router was a absolutely wonderful 'office in a box' appliance with a default network configuration  in place to make installation absolutely easy..

The Services Router in the LinksysOne application, required that certain VLANs were present, such as VLAN 100. Hence early SGE2000 software would not allow you to remove VLAN 100, as it was needed for the voice setup

If the SGE2000 or SFE2000 was put in layer 3 mode, it may then have to route the VOIP packets from VLAN 100 to the Services router VLAN 100.

To complicate this routing process, a discovery protocols,  bonjour was used  to discover the network devices such as phones. This protocol  could not have jumped over that routed boundary.

Hence the warning, leave the SGE on Layer 2 mode if the switch was used in conjunction with the LinksysOne services router.

Hope that little bit of history was interesting.

regards Dave
