Will OM4 Fiber Work with my 1GbE Fiber Transceiver?

As per IEEE 802.3 Clause 38, 1000BASE-SX requires OM2 (500 MHz·km for 850 nm) for max. 550 m reach. As a superset, OM4 is fine as well (there's little point buying OM2). With 10GBASE-SR the reach over ...

Will the Sticky MAC access policy prevent unauthorized hubs from connecting to a network?

As Jesse P explained, hubs do not have MAC addresses, but multiple devices connected to a hub would mean multiple MAC addresses on the switch interface, and what you suggest would detect that and ...

Cisco/Meraki switch SFP compatibility and dual link

It is the standard that you look for. In this case, it is 1000BASE-SX. Both of those transceivers use that standard, so they are compatible. It is much the same as Intel and 3Com 1000BASE-T copper ...

Does the theoretical limit of 54 Mbps apply to any WiFi protocol limited to 20 MHz wide channel, even on a 5 Ghz channel?

Other than the addition of 256-QAM [MCS 8], and (optional) 5-8 streams, you are correct. 802.11ac's advantages are small when limited to 20MHz. In the 5GHz band, there's no real reason to limit it to ...

HP 8206zl not delivering PoE 802.03at to Meraki AP

I found the issue, it has to do with the device itself, specifically an Meraki MR42 AP. When the 802.03at Meraki APs first powers up, it does so in 802.03af mode, thus limiting the power it can draw. ...

Device on VLAN is accessible from VPN but not from LAN

"LAN workstation" is in the 192.168.213.0/24 subnet - the same subnet you're using for "BAY x LAN". That is a very bad design. Unless you are using destination NAT and source NAT between those ...

Meraki MX84 VPN question

Not currently supported. This is likely due to the fact that AnyConnect establishes an IPSec Tunnel based on IKE v2 whereas the MX appliance (afaik) still uses IKE v1 for negotation.
