I have a stack of 450s I'm maintaining through the special 'ebay replacement program'. After a recent failure I swapped in a newer switch to a hybrid BPS/450 stack, but it's a newer SW rev than the existing units and the other 450s have dropped out of the stack (stack LEDs flash, units behave as...

I have a 420 stack (2, SW: 1.1.2.1 , 1.1.2.27) that seems to be working (I can remotely ping stations attached to ports on both units, so uplink fibre and stacking seem to be working OK.) What's happening is that the agent keeps vanishing for periods of 2 to 9 minutes, with uptime of about 30%...

I am adding a BPS2000 to a working stack of 450s, but can't get them to stack. Cables seem OK. Software is: 2.5.0.40 (BPS), 4.1.0.6 (450s), ISVN all 2 Switches start, and cascade up/dn LEDs light green on all 3 switches, then the 450's up/dn LEDs flash for a while, BPS2K LEDs remain steady...

I posted an earlier question, but things have got wierder. I had a problem updating a BS-420 stack via telnet. Diagnostics upgrade failed, both switches do not boot past the 'Testing Main Memory - Passed' message. Today, I put one on a bench, and tried the same with a console cable, TFTP...

I just tried to update a BS-420 stack, but it failed to restart. Now it gets as far as the memory test (passed) and freezes. This was the 'diagnostics' image. Had not upgraded the software image yet. This worked fine before on multiple units in my office (serial console). This stack was the...

I recently had a hub (Lattishub 2814, advanced agent 5.3.1) fail to load (flash error) so I found and tried downloading a new image to it. (5.3.3) It seemed really slow, so I backrev'd it to 5.3.1 The problem I have now is that a formerly 'advanced' agent now shows as 'standard'. Is this a...

Hi, I am trying to connect a new Baystack 380-24T to Accelar 1100-A (x2) I have 1000SX and 1000LX modules in the Accelars and 3xSX/1xLX GBIC in the 380. When I connect the LX fibre modules, the amber RX light on the accelar goes dark (Autonegotiate enabled on both units) If I fix Accelar to...

Hi, I am trying to work out the security features on old Lattishub stacks (2814/2803-Adv). I have worked out how to insert MAC addresses and get some basic intrusion control, but the settings seem volatile--lost after reset or power-off. This doesn't seem to make sense-it's a lot of messing...

After a recent DHCP server hardware replacement (W2K-SP4, MS-DHCP same IP, on (A) below) users on a 450 stack (sw C, below) have not been able to renew DHCP leases. I have only one subnet (10.1.0-3.x/22) and no vlans (or all one vlan?). If I set both ends of the link to 'trunk'/tagged, all...

Does the 'return' cascade cable of the ST1 cascade module make a performance difference or is it there only for redundancy? I only have the one cable right now between 2 switches, and it seems to work OK, but I have no way to evaluate the performance of the cascade link (that I know of)...

I have added an 1100R-A (SW 1.3.2) to supplement an original 1100. (has 2x 1102sx GB cards, hw rev.A) I can open it in Device Manager, but after about 30 secs, regardless of whether I'm reading/changing or leaving DM idle, the Accelar seems to drop the connection. (errors when saving/reading...

Anyone know what % of packets should be 'flooded' packets? I have just installed 2 450s (linked thru UTP for now), 1 has single 400-FX link to Accelar 1100. Flooded packet count increments fairly steadily on this port, about 1% of total RX packet count. Didn't notice this before. Other counts...
