Connecting two procurve 2510g switches

[Pieter 't Hart]

As from the "advanced trafic mangement guide", The dual personality port are no different then other network ports.
As seen in the image of my previous post, normal RJ45 ports, dual-peronality RJ45 ports. and dual personality modules are all useable to connect other switches.
Without GBIC or SFP module, the RJ45 connector is active. When a module is placed the corresponding RJ-45 port is automatically disabled.

From that point of view, the switches should not go down when multiply connected and spanning-tree is active, they should only block one path.
When configured as port trunks (LACP) multiple links can be active.

The 2510 "stack" only means a central point of management.
This is not the same as a cisco 3750-stack. But more like cisco "cluster" switch wich also uses a single command-switch to control the others.

I also have a few questions re. the 2510 G stacking capabilities - I'm used to using Cisco 3750's so presumed that the "stack" feature on the 2510 G was similar. Obviously not.

Can two 2510 G switches be setup so as to appear as a virtual single switch? Can the ports on switch two be part of a static vlan on switch 1?

Thanks.

Martin,
i think you'd better start a new thread, with a refference to this one.

but for your questions:
- no, the 2510's don't form a stack as the cisco's do.
The cisco 3750's form a single switching backplane (fabric) using special "stack cables".
the 2510's from a stack only to be managed from a central point.
cisco 2950's also had the "switch management cluster" wich is more similar to this HP-stack.

- yes, vlan's can (are designed to) span multiple switches .
you need to configure connecting ports on both switches as "tagged" in all vlans that must cross to the other switch.
then on each switch you configure a port as "untagged" in a vlan for a connected device must connect through this vlan.
