Router Interface Cards - Routing Feature

[Syed Farhan Ali]

Dear Team,

I have a Cisco 3945 Router and have all the slots available with me. The interface card that I am looking for should have the same functionality as HWIC-2FE.

I need a 4 or 8 port Routed Ethernet Card. I looked for "VWIC3-4MFT-T1/E1" interface card as I was unable to find 8 port card.

Please let me know if this card can be used as a Routed Interface Card (I need to terminate different ISP Links on this card).

Regards,

Farhan.

Believe the module you mention provides serial ports, not Ethernet ports.  Also believe it supports routing.

Higher density Ethernet cards often support routing via VLANs (you can dedicate a VLAN per port), but not as routed ports.

What you also do, if you have VLAN capable switch, use subinterfaces on a router port to a trunk port on the switch.

Hello Joseph,

Thanks for your response.

Is there a 4 port or 8 port routed ethernet interface supported on Cisco3945 Router (just like HWIC-2FE)?

No there is not - you have to go with 2 or 4 x HWIC-2FE depending on your requirements...

Card which you mentioned is for ISDN T1/E1 circuits...

Ok. I have two options in mind:

1) If I go for a EHWIC Card (Switch Ports) and configure interface vlan on them, will I able to terminate the ISP Links on them?

2) Is NM-8CE1T1-PRI Card providing WAN Connectivity on the Cisco 3945 router so I can terminate ISP links on them?

Regards,

Farhan.

1) could work but it's not meant for that - WAN side to ISP

2) Depends what are you terminating - if it's ISDN PRI then you could but I think you are not going to use that...

Stick with HWIC-2FE and you are fine...
