Hi,

I am unable to figure out which interface to configure for a sfp module on the 4400 router,

fibre is connected to the gi0/0/0 and the ethernet is connected to gi0/0/0. so how do i configure the fibre interface? please find attached photo of port connections

Try to swap cables - yellow and white.
In some cases you need to configure speed no negotiate under interface.
Otherwise configuration is the same as any other port.
#sh inv
should show you are SFPs recognised
(on switch you can see if SFP is recognised by issuing sh interface status - SFP should be listed)

Now I saw the picture. :)
Those look like dual-personality interfaces issue under interface

Can you both the ethernet and sfp ports?

No. Remove copper cable.

or is it that you have to use either ethernet or sfp? and not both?

Not both - dual personality ports are either SFP or RJ45. Not both.

So i have the link between the switch and the router up.

I can ping the connecting interface but nothing beyond that....
 
router sfp ip address is 10.194.2.1

TenGigabitEthernet5/14 10.194.2.3 is the sfp from switch to router.

i have added ip default gateway to point to interface of router which is pingable. Switch interface as below:

This is duplicated IP address issue (you can't have that):
switch
Vlan2                  10.194.2.1      YES NVRAM  administratively down down
router
GigabitEthernet0/0/1   10.194.2.1      YES manual up                    up



1. you have duplicated IP addresses
2. this IP address range overlaps with VLAN 2 - TenGigabitEthernet5/14 10.194.2.3      YES manual up                    up
3. On switch have a lot of interface VLANs - you need to issue ip routing on switch to be able to use all of those
4. since all vlans are in down down state that means that there are no ports assigned to VLANs

ip routing
interface vlan 2
 ip address 10.194.2.1 255.255.255.0
!
interface gi5/11
 ! not sure if switchport command is needed for 4400 (are ports in routed mode by default or not)
 ! but since you addigned IP address to interface I guess they are
 switchport
 switchport mode access
 switchport access vlan x
!

That was the network design that was provided, they had overlapping ips. Will raise it tomorrow but for now have changed it to as above and still unable to get the switch to communicate in different vlans.

All interface VLANs are in administratively down state
issue for all of you interface vlans
interface vlan x
no shut

check if routing is already configured
sh ip route

And to check what is expected for ip routing command issue
sh ip routing ?

Looks like ip routing is already in place since you have routing table.
configure default route to router

On router you should configure static route (or routes) to all networks configured on switch.
ip route 10.194.10.0 255.255.255.0 10.194.2.x            x - ip address of switch
ip route 10.194.11.0 255.255.255.0 10.194.2.x  
ip route 10.194.12.0 255.255.252.0 10.194.2.x            <--- optimization single route for 4 networks (range 10.194.12.0/24, 10.194.13.0/24, 10.194.14.0/24, 10.194.15.0/24)

Shouldn't the switch be switching between the vlans? how come we need a static route?
CERTIFIED EXPERT
Distinguished Expert 2018

Commented:
Switch will route between VLANs, but router need to know where other networks are located since those are not directly connected.

My previous post begins with
On router....
and end with
... to all networks configured on switch.
:)

Or you will use dynamic routing - and you will not need static routes (if supported by device licenses).

No problems thanks , i have added

Just as I sad
Vlan990                10.194.0.50     YES NVRAM  up                    down
There are no active ports in that VLAN.

Vlan900 is down down - reason VLAN 900 is not created on switch.

You need to add default route on edge switch.
If you have management VLAN in the same IP address range as routed interface you have to change management vlan IP address range.

Or you need configure port to router as access port in VLAN 2

interface te5/14
 no ip address
 switchport
 switchport mode access
 switchport access vlan 2
!
interface VLAN 2
 ip address 14 10.194.2.5  255.255.255.0

It's your choice.

And please configure spanning tree mode as RPVST. :)
