For BGP in a multi-homed configuration advertising public IP blocks, the AS number should be a valid public AS number allocated by the regional internet registry (RIR). Numbers in the private AS range (64512-65534) are not suitable for public Internet announcements.
63472 falls in the public AS range (16-bit AS numbers below 64512).
64813, 65535, and 65218 are in the private or reserved range.
Therefore, 63472 is an example of a suitable public AS number.

2024-04-04T08:35:38.312254+00:00 ICX-Core-1 hpe-vaxd[2167]: Event[701|LOG_INFO|AMM1/1|VSX2 state local up, remote down] indicates that the local VSX member is up, but the remote VSX member is down. In a VSX pair, both switches must be operational for full redundancy and synchronization.
This log means the secondary VSX switch (remote) is down or unreachable, causing loss of synchronization and possibly traffic failover issues.
Option B (keepalive detection) is related but the event specifically shows the state of the remote switch being down.
Options C and D refer to LAG or interface state, which are not what this log entry describes.

DHCP snooping requires to be enabled globally before it will function correctly. If it is not enabled globally, even if enabled on VLAN interfaces, DHCP snooping will not work.
Enabling authorized DHCP servers (A) or trusted interfaces (B) is necessary but only after global enabling.
Enabling DHCP snooping on VLAN (C) is not sufficient without global enablement.
Therefore, enabling DHCP snooping globally is the first step to activate the feature.
