What's up with making DHCP reservations based on MAC addresses? I'm using the client-identifier command after setting the host ip in the dhcp pool, and prepending an 01 to the MAC address I see for the interface of a machine (say a Linux one). I noti...

So this all takes place on a Catalyst 9200 Layer 3 switch, where VLANs have virtual interfaces (SVIs). I have several networks of 10.1.x.x that are our main data subnets (VLANs 25, 26, 29, 30). There is a lab network (VLAN 20) at 172.16.20.0 /24 that...

Hi,We noticed that on one of our phones in particular, the 8861 (which is connected to the network wirelessly due to lack of available ethernet ports at that desk), the volume sounds rather faint, especially with external calls, even if the volume is...

I want to set up a VLAN 20 (172.16.20.0 /24) to have internet (which it does) but not be able to reach any of the other VLANs on the switch. However, I want the other VLANs on the switch to be able to reach it (say VLAN 26 at 10.1.26.0 /24 and VLAN 2...

Hi, it seems HTTPS should be enabled and activated for the EWC, but I'm still getting the no https indicator on my browser when going to the IP for the web GUI:What other steps should be taken?

By the way, would you know how to make that 172.16.20.0 VLAN 20 network able to get an address via DHCP from a server in the 10.1.26.0 subnet, given this access list? I set up a dhcp relay and moved the dhcp server to 10.1.26.5 rather than using the ...

No suggestions at all?

Hm, I set that VLAN Y network as a lower security level than the others, and it has its own inside interface separate from the rest of the main network and VLANs.For access control list rules for that interface on the firewall, I allowed traffic from...

Thanks. For this configuration, does VLAN Z/20 need to be connected to a separate physical interface on the firewall than the other VLANs? Because now they all go through the same one.
