Is there any possible way to get 100mb SFP's to work with a 4506 line card - WS-X4448-GB-SFP

Even if it's not supported.

If possible I would like to do this temporarily until the users get cut-over to 1gb connections.

Than you,

Hi!

You can try this solution, however it is not recommended. Due to potential problems with your device warranty.

(config)# service unsupported-transceiver

Warning: When Cisco determines that a fault or defect can be traced to
the use of third-party transceivers installed by a customer or reseller,
then, at Cisco's discretion, Cisco may withhold support under warranty or
a Cisco support program. In the course of providing support for a Cisco
networking product Cisco may require that the end user install Cisco
transceivers if Cisco determines that removing third-party parts will
assist Cisco in diagnosing the cause of a support issue.

(config)# no errdisable detect cause gbic-invalid

Hope it helps, regards!

I recall someone I used to work with using this command for non-Cisco SFP's. But the device supported 100/1000. The WS-X4448-GB-SFP says that it only supports 1gb. Has the command worked on cards that only support 1gb SFP's?

Thank you,

Eric

Hi Eric,

I think you will need to source one of the following as the 4448 only supports 1Gig SFPs:-

Classic Fast Ethernet Fiber Line Card

Figure 28 shows the WS-X4248-FE-SFP.

Figure 28.    WS-X4248-FE-SFP Cisco Catalyst 4500 Fast Ethernet Switching Module, 48-Port 100BASE-X (SFP)

WS-X4248-FE-SFP:

●   48-port 100BASE-X (SFP optional)

●   Customers can mix and match 100BASE-X SFP optics on the same line card

●   IEEE 802.3, IEEE 802.3ah, IEEE 802.3x flow control

●   Enterprise and commercial: fiber-to-the-desktop applications

●   Service providers: running point-to-point Fast Ethernet to the home or business (FTTH)

WS-X4148-FX-MT:

●   48-port IEEE 802.3 100BASE-FX Fast Ethernet

●   Connectors: MT-RJ

●   Distance: 1.2 miles (2 km) over multimode fiber

●   Status: green (operational), red (faulty)

●   Link: green (operational), red (faulty)

●   Standards: IEEE 802.3

●   Service provider: Run point-to-point Fast Ethernet fiber to the home (FTTX)

●   Enterprise and commercial: designed for server farms and switch-to-switch applications

I have another 4500 that has the newer gig line card - WS-X4640-CSFP-E, and I was able add a 100mb SFP and it worked. So I thought that if I used the same IOS on the older card (WS-X4448-GB-SFP) it would work, but it will not load the image. It keeps reverting back to the older image. The only difference is the one with newer card is a 4503 and the one with the older card is a 4506.

I have the boot statement in there for the new image. The way the files are displayed on the 4506 look different from the 4503:
