How to set 10G link speed without autonegotiation?

Sat Jul 21, 2018 3:50 pm

I have CRS317 and CRS326. When auto-negotiation is enabled I'm getting both links to operate at 10G speed no problem. However if I set auto-negotiation to "no" they operate at 1G speed. How do I properly set fixed 10G speed? Here's config of interfaces on both switches and log:

25 RS name="sfp-sfpplus2" default-name="sfp-sfpplus2" mtu=9000 l2mtu=9112 mac-address=CC:2D:E0:51:8E:F9 orig-mac-address=CC:2D:E0:51:8E:F9 arp=enabled arp-timeout=auto loop-protect=default 
      loop-protect-status=off loop-protect-send-interval=5s loop-protect-disable-time=5m auto-negotiation=no advertise=10M-half,10M-full,100M-half,100M-full,1000M-half,1000M-full 
      full-duplex=yes tx-flow-control=off rx-flow-control=off speed=10Gbps bandwidth=unlimited/unlimited switch=switch1

14:32:13 interface,info sfp-sfpplus2 link up (speed 1G, full duplex)

15 RS name="sfp-sfpplus15" default-name="sfp-sfpplus15" mtu=9000 l2mtu=9112 mac-address=CC:2D:E0:58:18:DE orig-mac-address=CC:2D:E0:58:18:DE arp=enabled arp-timeout=auto 
      loop-protect=default loop-protect-status=off loop-protect-send-interval=5s loop-protect-disable-time=5m auto-negotiation=no 
      advertise=10M-half,10M-full,100M-half,100M-full,1000M-half,1000M-full full-duplex=yes tx-flow-control=off rx-flow-control=off speed=10Gbps bandwidth=unlimited/unlimited 
      switch=switch1

14:33:48 interface,info sfp-sfpplus15 link up (speed 1G, full duplex)

When I disable auto-negotiation on CCR1009 SFP+ cage I'm getting "no-link" at all. Not even 1G

Edit: Ok i't s because CCR1009 actually properly tries to establish 10G with autonegotiation disabled. Unlike CRS317 and CRS326

Hello,
Please follow the below steps,
1. Delete the no-auto-negotiation statement and commit the configuration.
2. Set the link speed to 10 or 100 Mbps, set no-auto-negotiation, and commit the configuration.

Hope it will helps you!
