I will give an example of cable diagnostics on Foxgate switches, for the test I will take the Foxgate S6224-S4 switch.Continue reading “Cable test on Foxgate S6224-S4”
To update the FoxGate switch firmware via BootROM, I will describe a few simple steps.Continue reading “FoxGate Switch Firmware Update via BootROM”
I will use the Foxgate S6224-S2 switch as an example.Continue reading “FoxGate Switch Firmware Update”
On the test I will configure the Foxgate S6208-S1 (R2.0) switch.Continue reading “Configuring Foxgate S6208”
I’ll write below a few popular SNMP OIDs for FoxGate switches.

On the test, I will update the firmware on the FoxGate S6224-S4 switch (R5) with version 188.8.131.52 (R0058.0010).
I noticed that on this version of the firmware on the switch, the Vlan management interface often fell off, and the switch performed its functions, but was unavailable.
For example, I’ll take a FoxGate S6224-S4 switch; on other models, the configuration is almost the same.
First, enable the dhcp snooping function:
ip dhcp snooping enable

First of all, let’s look at the statistics of active traffic on ports:
show interface ethernet counter rate
Then we’ll look at the packet counters, especially pay attention to the BroadCast (pkts) column:
show interface ethernet counter packet
For a specific port, we will execute the command to view the statistics of the network interface several times:
show interface ethernet 1/25
And let’s pay attention to how the incoming and outgoing values of the broadcast packets change, if they do not change, then the broadcast packets do not go through this port, if the digit increases rapidly, then maybe there is a broadcast storm.
If necessary, we will enter the competing mode and set the limit of transmitted broadcast packets in kilobits (minimum value 1) for the required ports:
config Interface Ethernet1/1 storm-control broadcast 50 Interface Ethernet1/2 storm-control broadcast 50 Interface Ethernet1/3 storm-control broadcast 50 ...
Note that with a low broadcast bandwidth limit, DHCP broadcast requests from clients can also be blocked.
For the test, I will configure on the Foxgate S6224-S4, S6224-S2, S6208, and so on.
Connect to the switch through the console or telnet and switch to the configuration mode:
Let’s create a group of isolated ports and add ports to it that do not need to see each other (in my case, clients are from 1 to 24):
isolate-port group users isolate-port group users switchport interface ethernet 1/1-24
The command is the same on all Foxgate switches, but port numbers may differ, for example on S6224-S2 I configured it like this:
isolate-port group users isolate-port group users switchport interface ethernet 0/0/1-24
After adding the ports to the group they will not see each other, but they will see the ports that are not in the group, I have the 25 port is the uplink on which the Internet comes, because it is not in the group, it sees all the ports, and the ports that the groups see him.
Let’s see the list of ports in the users group:
show isolate-port group users
Leave the configuration mode and save the settings:
