Anyone got any experience with these as am having some difficulty trying to setup a vlan trunk via there lovely web interface, my web searches haven't turned much up apart from that cisco trunks and netgear trunks are 2 diffrent things

Thanks in advance

what s/w are you using to set up the virtual Lan?

oops sorry Thomas, misread that post. I thought you were setting up a vlan with vmware. We use these all the time at work, but I see your referring to that web interface. Which is total pants! I had a simliar problem with netgear and belkin router using their software interface to setup and configure the ports. In the end I used IE.

 

Can you give us some more details, such as error message, screen shots or what exactly your having a problem with? is it the settings, the ports? Or the fact you can't connect??

 

Sorry UCM ofcource i can, I'm messing about with tagged vlans. The equipment I'm using is a Cisco 877 Sec router and 1 Netgear GS748TS Smart Switch, from my understanding i need to add 1 port(uplink port to router) to all vlan(trunk) and tag the traffic, this is where I'm having the problem as in the GS748TS web interface there is no way that i can see to achive this

[Edit]
I suppose i could be getting confused due to my lack of knowledge on vlans

I can tag port 1(router attached) on all the vlans via the vlan membership configuration page but not sure that this automatically trunks it

 

Do you know what firmware version you have on the smart switch. :hhhmmm just having a lookie at the specs of the switch I sure the uplink was automatic???

Have you seen the review?

"An intuitive, web-browser interface offers simple switch management, making it a snap to monitor switch performance, configure ports, even set up trunks, VLANs, and prioritization" that bit cracks me

 

ThomasMc,

Questions:

1. How have you determined that you have a problem?
2. What IOS version is running on the Cisco 877 router?
3. How did you determine that the Netgear GS748TS Smart Switch supports VLANs?

 

Err it does say in the spec's "IEEE 8021.Q VLAN (128 groups, Static) "

Although I'm not sure if the cisco router supports 8021.Q???

Just having a look on google for it?

 

Answers:

1. 3 out of 4 vlans are not being serviced by the routers DHCP, Internet etc etc
   ping tests on the vlans reveal no traffic is passing between vlans.
2. 12.4 T.
3. After reading the Data sheet and user manual i determined that vlans where supported, although they mentioned trunking in these documents i have found out that it refers to a Netgear LAG(Link aggregation) port function or Port Teaming.

 

OK I can't find the exacy specs on the 877 but found the specs on the 870 series..

Cisco 870 Series Integrated Services Routers for Small Offices

EDit: sorry just found it halfway down the page:_ General Router Features
• 4 802.1q VLANs on Advanced IP Services IOS image

 

its a
CISCO877-SEC-K9 -- Cisco 877 ADSL Security Bundle with PLUS Feature Set

 

Not sure about the ACL, but when i run the vlans native and use a seperate physical interface for all 4 of them on the router without the switch each client on the interface gets the correct ip for that vlan and tinternet is A ok and all vlans can talk(with the same ACL's), when i let cisco handle the trunking but i want to run all the vlans over a single link to the router, so in my understanding the trunking should be done at switch level

[edit]
i use SVI's on the cisco vlan config that should pass the traffic as far as the router is concerned

 

ThomasMc,

Exactly which version of Cisco IOS, including the number and letter in parenthesis after the 12.4T? Do a "#show version" on the Cisco 877 to find out.

 

UCHEEKYMONKEY,

IEEE does not have a "8021.Q" standard. They do have a "802.1q" standard. When you're referring to "spec's," are you talking about the Cisco 877 router or the Netgear GS748TS Smart Switch?

 

It reads 12.4(6)T9, Release Software (fc2)

 

i thought i would share more info on my setup to see if anyone can spot a problem

Cisco 877 on Port 1 or 1/g1
on the Netgear Switch all ports have PVID of 1
Via the Vlan Mebership page i have added port 1 to all vlans and tagged the port

Port 2 or 1/g2 is an untagged member of vlan2
no DHCP traffic is being serviced on vlan2
from what i have managed to read on the net this should be working so maybe its the router setup thats causing me jip

after looking at my last post i noticed set my subinterfaces wrong (note to self "/" physical "." sub), will test in the morning and report back

 

nope that didn't work, shyzer tryed something along the lines of

Code:

interface FastEthernet0
 no shutdown
!
interface FastEthernet0.1
 switchport mode access
 switchport access vlan 2
!
interface FastEthernet0.2
 switchport mode access
 switchport access vlan 3
!
interface FastEthernet0.3
 switchport mode access
 switchport access vlan 4
!
interface FastEthernet0.3
 switchport mode access
 switchport access vlan 5
!

 

Try creating a trunk from one of the switchports, e.g.:

int f0
switch mode trunk
switch trunk encap dot1q
switch trunk allow vlan all

Set the ip address for each vlan on the vlan interface. You may have a problem with the number of vlans as the advanced security image only supports a measly 2 vlans, I think. Advanced ip services is the image you'll need.

Also, make sure the native vlan is the same on both the switch and the 877.

Thanks for the reply Spicey, will try this in the morning .

Its a CISCO877-SEC-K9(28/128 although i was thinking about getting a 16mb flash upgarde) : Cisco 877 Security Bundle with Advanced IP Services(would i be correct in saying that it can have a max of 4 vlans?)
