Bandwidth configuration via Switch

dianawinsky — Thu, 26 Sep 2024 07:01:13 GMT

I am curious about configuring bandwidth restrictions for specific VLANs through a switch. For example, restricting a guest Wi-Fi VLAN to 10 Mbps. While this can typically be done via a wireless controller, the customer requires this to be configured on the switch.

Option 1: If using access switches with a GUI, should I configure the bandwidth restriction for selected VLANs under the bandwidth section for each port that belongs to the VLAN, or should I use the VLAN ingress limit to specify the restriction for the VLAN itself, since the bandwidth section may be time consuming due to configuration for each port ?

Option 2: If configured on the core switch, what would be an example CLI command to implement this in a simplified manner?

Cannot speak to GUI configuration, but CLI configuration would depend on the specific platform and its specific IOS.

In general, bandwidth limitation might be done via an ingress or egress policer or via an egress shaper.

does police average 1000000 equivalent to 10Mbps? I think it's for 1Gbps

If I remember correctly, policer (and shaper) value is in bps.
