Traffic to TEFP, which is not part of BDI or CFM, is looped back based on filters. Hence, dscp/prec marking with ELB is not supported. The 元 packets that must be routed is also not looped back.
Ethernet loopback mac#
If the packet has a destination MAC address and a destination IP address similar to the BDI MACĪnd IP address, then the packet is punted and is not looped back. Random unknown IP packets may be looped back with MAC address swap, but RSP3 module does not support IP address swap. ELB is applicable to all the VLANs configured in EFP on the RSP3 module. Internal ELB is not supported when the physical interface port state is down.ĭata filtering of loopback is not enforced for the traffic coming in the opposite direction.įiltering based on specific VLAN is not supported. Ethernet loopback sessions are supported only on EFPs and Trunk EFPs on the RSP3 module. Loopback sessions cannot be initiated on a port configured with SPAN or RSPAN.Įthernet loopback is not supported on a range of dot1q tags.Įthernet Data Plane Loopback is affected on STP enabled interface.ĭynamic addition of rewrite ingress tags with default EFP is not supported.ĭynamic changes at EFP and interface level are not supported when Ethernet Data Plane Loopback is active.Įgress EFP is not updated for external Ethernet data plane loopback statistics.įor internal Ethernet data plane loopback ingress and egress interface statistics are not updated on interface, where internalĮtype, VLAN, COS, src-mac, and llc-oui based loopback traffic filtering is not supported. Local SPAN and ELB cannot be enabled on a physical interface at the same time. This scale is supported onĮthernet loopback (terminal or facility) session can be active on an EFP at any This scale reduces if RSPAN or SADT is configured. This scale is supported onĪ maximum number of 12 terminal loopback sessions can be created per system, provided 8 sessions are with Dot1Q and 4 sessionsĪre with Dot1Q and destination MAC address. This scale reduces if SPAN or RSPAN is configured.
Ethernet loopback series#
Internal loopback sessions configured must be within the 1 GB reserved bandwidth for Cisco ASR 900 Series RSP2 Module.Ī maximum number of 20 facility loopback sessions can be created per system, provided 16 sessions are with Dot1Q and 4 sessionsĪre with Dot1Q and destination MAC address.
Port shaper cannot be bypassed in facility loopback.įacility and terminal Ethernet data plane loopback (ELB) are not supported on dot1ad nni interface. However I can't tell if it was the device type or the file contents that have changed with that.Loopback on routed port infrastructure isĮtype, src-mac, and llc-oui based loopback traffic filtering is not supported. Strangely enough, the original setting worked for me for more than 6 months, until I decided to clean out the packages installed on my system. Wifi (iwlwifi), 28:C6:3F:CD:A1:9F, hw, mtu 1500Īdding that type to the exceptions in /usr/lib/NetworkManager/conf.d/nf did work for me: unmanaged-devices=*,except:type:wifi,except:type:wwan,except:type:ethernet "Intel Wireless 8260 (Dual Band Wireless-AC 8260)" While the advice to create an empty /etc/NetworkManager/conf.d/nf file worked for me, I found another way to fix this.Ĭalling nmcli, I noticed that my ethernet device isn't classified as one of the types ( wifi, wwan) that are excluded from the unmanaged-devices clause, in contrast to the WiFi device, but as ethernet: $ sudo nmcliĮnp0s31f6: verbunden to Kabelgebundene Verbindung 1Įthernet (e1000e), 54:E1:AD:FC:E1:22, hw, mtu 1500
Or the old way: sudo service network-manager restart
The reboot, or restart the Network Manager service: sudo systemctl restart NetworkManager Sudo touch /usr/lib/NetworkManager/conf.d/nf Sudo touch reported a different location for The file nf so the commands should be: sudo mv /usr/lib/NetworkManager/conf.d/nf /usr/lib/NetworkManager/conf.d/nf_orig If the that didn't solve the problem, try running the following (backup orig file, and create 0 bytes file instead) sudo mv /etc/NetworkManager/conf.d/nf /etc/NetworkManager/conf.d/nf_orig Try running the command below: ip link showĪnd look for a device name similar to enp8s0 and substitute it in the original command.
Ethernet loopback Bluetooth#
The following bug in Ubuntu 16.10 might be related: network-manager does not manage ethernet and bluetooth interfaces when Ubuntu 16.10 is installed using chroot/netboot methodįirst try running the following command: sudo nmcli dev set enp8s0 managed yes
