Is there any cheap way to convert from CX4 to RJ45?

CX4 is a dead connector and fell into disuse a long time ago. The ProCurve 2900 went end-of-life ~13 years go. Your internet provider is giving you a 10GbE handoff, but you can use a 1GbE port on ...

HP Procurve 2910 Inter VLAN routing partially working

A 2910 with activated ip routing routes from and to any VLAN that it has an IP address assigned in. So, if a node can't reach one VLAN subnet from another it's likely not in the correct VLAN. ip ...

ProCurve 2910al-48G-PoE+ (J9148A) configuration

Short answer: no go. The 2910al is a layer 3 switch, meaning it can't do any NAT between private and public IP addresses - that would require a layer 4+ switch. So, need another router for NAT. I'm ...

Your VLAN can talk to each other because the switch does routing between them. To prevent certain VLAN to talk to certain VLAN, put ACLs in place and allow only what you want. However, I recommend ...

Two untagged VLANs on one port (ProCurve)

You can't have two untagged VLANs on a single switch port, and wouldn't want to do that regardless. You'll likely need two NICs in your machine, one on each VLAN, if you can't route between the ...

HP Procurve STP Path Blocking

Essentially, SW2's STP priority doesn't matter as it's only used for root election. Since SW4's path costs are 1G+1G across SW3 but 1G+10G across SW2, the latter is set as root path and the former is ...
