Two VMWare ESXi hosts, each with 2 10GB NIC Storage with 2 10GB NIC Where's the storage? how would the ESXi hosts communicate with the LAN? The host should use dedicated NICs for LAN and SAN. For a fully redundant connection you need at least two NICs (each via a separate switch). Depending on your redundancy requirement, that means a minimum of four NICs ...

Short answer: Do NOT use hybrid mode. If you're after mixed tagged/untagged VLAN trunking, that's not what hybrid mode means. Hybrid mode is used with protocol-based VLANs. Without proper configuration, frames all end up in the default VLAN. The only common use case for hybrid mode is a legacy end node that doesn't support tagging but where you still want to ...

First- as many others PT is not IOS and many functions are either limited or do not work. Second: Cisco defines two privilege levels by default (1 and 15) any non-default privilege level can be defined with privileges set. You may be able to view the configuration by using the command “show run all” but I doubt the command works. For more reading please ...

Incidentally, I stumbled on a likely explanation for the described problem. Your suspicion is most probably correct: the switch does seem to verify the firmware version in the config with the actually running version. When exported using the add-ignore-tag option, the first line is changed to e.g. ; J9850A IGNORE Configuration Editor; Created on release #KB....

Basically, you need to make up your mind which device your clients should use as default gateway: the OPNsense - then inter-VLAN routing goes that way, too - or the L3 switch, that in turn uses the OPNsense as default gateway. If you use the OPNsense for inter-VLAN routing, you set up firewall rules for which connections are permitted. Note that the OPNsense ...

There is one option available. Create a new VLAN and create new DHCP scope for this VLAN Assuming you created new VLAN as VLAN 20 Switch (config)#ip dhcp pool Vlan20 Switch(config)#network 192.168.X.X 0.0.255.255 Switch (config)# default-router ip 192.168.1.1 Switch (config)#dns-server 8.8.8.8 Also create the same VLAN 20 on downstream access switches, and ...

Now they have 230 devices and They are going to increase device count by 100. Within the same subnet? Then you'd have to supernet that subnet to e.g. 192.168.24.0/23. I cannot change subnet and increased usable IP addresses count because there are many dependencies. Adding another subnet/VLAN is a better option anyway. As Jesse's already answered, that ...

Questions about protocols above layer 4 are off limits here, however, as a very basic explanation on a layer 2 and layer 3 level, you cannot have multiple VLANs using the same DHCP pool (same subnet). Each VLAN would need a separate DHCP pool (separate subnet) to assign addresses from. For example: VLAN 100: 192.168.1.0/24 VLAN 200: 192.168.2.0/24 Just to ...

you could add a second range to another vlan. If the switch is a layer 3 switch, it shouldn't be a problem to connect to eachother. If not, a downtime is necessary to adapt the existing one.
