Cisco 837 Features

[Ali Norouzi]

Hello

I have some questions about Cisco 837. I couln't ding a good datasheet for that.

1- Does Cisco 837 4 port ethernet switch is a managed switch?

2- How many VLANs does it support?

3- Does it supports EIGRP and OSPF anf BGP?

4- Does it supports SVI?

As I compared it with Cisco 877 I found that 837 only support ADSL and not ADSL2. Also some firewall features of 877 is better than 837. Do you know other points?

Thank you

Hi;

its a managed device.

It supports Routing protocol – IGRP, RIP-2, GRE

It supports SVI:

Please rate if it helps.

Here is thge datasheet to the 830-series:

http://www.cisco.com/en/US/prod/collateral/routers/ps380/ps4874/product_data_sheet09186a008010e5c5.html

The most important point is that this model is End-of-Support and you don't get any recent IOS for the 837.

For the 877 EOL/EOS is also anounced, but not yet reached.

Hi Ali,

i had just to replace quite enough routers 837 and 877 since on their EoL/EoS. Go for 887VA and you won't have any problem if xDSL is the encapsulation you need. Just a note, don't implement BGP on a so small router especially if you want full BGP routing table...

Hi Alessio,

I'm agree with you that newer models are better but I'm in special situation and needs to know its features.

Scince it doesn't support ADSL2, did you had issue with line quality or cross talks on ADSL?

Is that support EIGRP and OSPF?

Is the 4 port switch is manageable and SVIs is supported?

Thank you

[Karsten Iwen]

Is that support EIGRP and OSPF?

Yes, both are supported, but you need the "PLUS"-Feature-Set.

Is the 4 port switch is manageable and SVIs is supported?

The management of the Switchports is highly restricted. You can set speed/duplex per port and one interface can be configured as a DMZ. Thats all:

Thank you Karsten.

In DMZ document there is examples that IP address configured undet ethernet interfaces. Is it possible to configure IP under SW ports of this router? In 877 it's no possible and to do that interface vlan must be configured.

[Karsten Iwen]

As far as I remember it is not possible. The "switchports" fa1 to fa4 is for physical settings (speed and duplex), while interfaces E0, E1, E2 are for the IP-config. But we dumped our last 830 about four years ago, so I don't remember exactly.

Hi ALi,

it is not possible unless implementing a sort of reduces features inter-vlan routing.
