ASR1002 onboard interfaces: fixed gig or not ?

[gnijs]

Hello,

Just wanted to know if someone could confirm if the onboard interfaces on an ASR router (4x on ASAR1002, 6x on ASR1002-X) are fixed gigabit or are they 10/100/1000 ?

Next: I assume the interfaces on the 8port Gigabit SPA module are fixed gigabit speed ports (why otherwise sell a 10/100 8port SPA module also ?) no ?

regards,

Geert

Hi,

They are all SFP based Gig ports. So, fiber Gig ports and not 10/100/1000.

See table-8 in this link:

It seems the ex-GLC-T (copper, now SFP-GE-T) is supported.

See: http://www.cisco.com/en/US/prod/collateral/routers/ps9343/qa_c67-496324.html

Q. Which optics are supported on the native built-in Gigabit Ethernet ports of the Cisco ASR 1001, ASR 1002, and ASR 1002-X?

A. Built-in Gigabit Ethernet ports support the same optics as the Cisco 5-Port Gigabit Ethernet SPA, Version 2 (SPA-5X1GE-V2).

Q. Which SPAs support the Cisco 1000BASE-T SFP Transceiver Module for Category 5 Copper Wire
(SFP-GE-T)?

A. The Cisco 1000BASE-T SFP transceiver module for Category 5 copper wire  (SFP-GE-T) is supported on the Cisco 5-, 8-, and 10-Port Gigabit  Ethernet SPAs (SPA-5X1GE-V2, SPA-8X1GE-V2, and SPA-10X1GE-V2,  respectively) and the built-in Gigabit Ethernet ports of the Cisco ASR  1001 and ASR 1002. The Cisco 2-Port Gigabit Ethernet Shared Port  Adapter, Version 2 (SPA-2X1GE-V2) has two built-in copper interfaces.

-> note : this one is missing ASR1002-X ??

Q. Is auto-negotiation supported with the Cisco 5-, 8-, and 10-Port Gigabit Ethernet SPAs?

A. No. Auto-negotiation is not supported. The 1000BASE-T SFP transceiver  module (SFP-GE-T) supports 10/100/1000 speeds, which you must explicitly  configure using the speed command. Only full-duplex mode is supported; you must configure it using the duplex full command.

So it seems you can get 10/100/1000 speeds on both the onboard and SPA interfaces.

This is strange as this document

http://www.cisco.com/en/US/docs/interfaces_modules/shared_port_adapters/install_upgrade/ASR1000/ASRintro.html

does not list the SFP-GE-T as valid. One of these two documents must be wrong.
