Can a DB9000 have spanning tree disabled. ^ If you mean a DECbridge 900MX, nope, spanning tree cannot be disabled. Why would you want to do that? Bob | |||||

"Disabling" spanning tree and "turning off" spanning tree are two very different concepts. By disabling a port on the bridge, you disable that port from bridging. This is what the red/green switch on the port section of the HUBwatch bridge summary view gives you. One reason to disable a bridge port is to segment a problematic part of the extended LAN from the rest. "Turning off" spanning tree on a port says that you continue bridging on it but don't participate in the spanning tree algorithm, that is, neither process received hellos nor send out any. The current version of the bridge does not allow you to do this, but it's on the list for a future version. (It is something that few customers want, since with the algorithm turned off you neither have loop protection nor backup capability. However it may be useful to separate "domains" on the same extended LAN.) Anil | |||||
1307.3 | Disable spanning tree is defined in MIB elan v2.9 | COL01::WELZEL | Uwe Welzel, NIS, Cologne | Fri Nov 04 1994 07:00 | 12 |
Hello, again disable spanning tree on DB900MX. As mentioned in .2 "Turning off" spanning tree is not allowed in the current bridge version. But in the "Vendor MIB elanext v2.9" is an object for turning off spanning tree "ebrSpanTurnOff" defined in the "ebridge" group. When will this function be supported by the DB900MX ? Thanks in advanced and best regards Uwe |
