1801 router performance

So I use my 1801 to route between vlans set up on a TP-Link gigabit switch (router on a stick topology).

The only NATting I use on the router is out to the Internet.

Connected to the switch is a VMware ESXi host that has virtual machines on two subnets.

I find that file transfers between virtual machines based on different subnets can be as low as around 10 MB/sec.

This makes sense as the 1801 only has 100Base-T ports running at 100 Mb/s.

If I use a layer 3 gigabit switch to do the inter vlan routing such as a Cisco SG300-10, will I get transfer rates closer to what gigabit LAN can normally provide?

That is normal. The 1801 was designed to be used as ADSL router for the speeds that were normal many years ago, not for inter-vlan routing.

For that, use a layer 3 switch.

Hey Paolo,

Thanks for the quick response.

Do you know if the SG300-10 layer 3 switch can do inter vlan routing as although it has a CLI, it doesn't run IOS.

From reading the document link below, it sounds like I'll need a Catalyst switch.  Is this right?

About that, please ask in "small business switches".

thank you for the nice rating and good luck!

Hi,

Cisco 1801 will support Intervlan also.

By enabling dot 1Q, you can creat a multiple sub interface and for those sub interface you can give your ip address

like below

Router0

Router(config)#int fastEthernet 0/0

Router(config-if)#exit

Router(config)#int fastEthernet 0/0.10

Router(config-subif)#encapsulation dot1Q 10

Router(config-subif)#ip address 10.1.1.1 255.255.255.0

Router(config-subif)#no shutdown

Router(config-subif)#exit

Router(config)#int fastEthernet 0/0.20

Router(config-subif)#encapsulation dot1Q 20

Router(config-subif)#ip address 20.1.1.1 255.255.255.0

Router(config-subif)#no shutdown

Router(config-subif)#exit

Please note that the 1801 does not have enough performances for inter-vlan routing, the very reason why the OP has posted this thread..
