locateMac.py ?

Hello, does anyone already tried the locateMac.py scrip? I’m not able to run it from any switch. Thanks!

SNMP traps for MAC move, learn, and age events

Description This feature adds three new SNMP traps for MAC move, learn, and age events: aristaMacMove, aristaMacLearn, and aristaMacAge, respectively. These are defined in the ARISTA-BRIDGE-EXT-MIB. Platform compatibility This feature is supported on all platforms. Configuration The aristaMacMove, aristaMacLearn, and aristaMacAge traps are disabled by default. They may be enabled, like all traps, with the “snmp-server enable traps” command. They are grouped under the “bridge” category, so they can all be enabled at once with “snmp-server enable traps bridge”, or they can each be enabled/disabled individually, as shown below: switch(config)#snmp-server enable traps bridge ? arista-mac-age Enable aristaMacAge trap arista-mac-learn Enable...

vEOS – Logical VTEP with MLAG – VXLAN interpreted on MLAG Peer

Hello all, Please see attached picture for network topolgy. I try to use VXLAN with HER for DCI, together with BGP&BFD as routing protocol (for underlay) between Site A and Site B.– Site A: VLAN100 mapped to DCI VNI 10100– Site B: VLAN1100 mapped to DCI VNI 10100– spine1&spine2 as mlag peers with logical VTEP– spine3 as single VTEP– ports for DCI configured as L3 routed (no switchport)– EBGP between spine1 and spine3 as well as spine2 and spine3– VLAN4093 between spine1 (10.0.1.1) and spine2 (10.0.1.2) for re-routing in case one DCI is down– IBGP between spine1 and spine2– target...

Timestamping Deep Dive – Frequent Questions and Tips on Integration

  Introduction Accurate packet timestamps are essential for network event correlation and performance analysis. The Arista 7150S provides hardware timestamping with nanosecond granularity and ≤10ns precision. Timestamping is applied in hardware on all packets, at line rate in parallel. The timestamping format and implementation is detail is this article: https://eos.arista.com/timestamping-on-the-7150-series/ The present article explains in more details the internals of timestamping on the 7150S, and provides an overview of expected behaviours, as well as tips for integrating with your tooling environment.   1) How does Timestamping work ?   Timestamping on the Arista 7150S is a function of the MAC...
