The difference between the two forms of authentication is in the level of security provided. In case of clear text authentication, the password is specified as text in the authentication TLV, making it possible for an attacker to break the authentication by sniffing and capturing IS-IS PDUs on the network.

By default if there's a hostname configured on the switch, it is used as the IS IS hostname. It is also possible to

Arista switches provide several mirroring features. Filtered mirroring to CPU adds a special destination to the mirroring features that allows the mirrored traffic to be sent to the switch supervisor. The traffic can then be monitored and analyzed locally without the need of a remote port analyzer. Use case of this feature is for debugging and troubleshooting purposes.

In an MLAG setup, routing on a switch (MLAG peer) is possible using its own bridge/system MAC, VARP MAC or VRRP MAC.

MLAG currently checks for basic MLAG configuration to be consistent (e.g. domain id) before formation with the peer.

The nexthop group feature allows users to manually configure a set of tunnels. Nexthop group counters provide the ability to count packets and bytes associated with each tunnel nexthop, irrespective of the number of times it appears in one or more nexthop groups. In other words, if a nexthop group entry shares a tunnel resource with another entry, they will also share the same counter.
