of indexes. For example, 1-3, 5 indicates 1, 2, 3, 5.
sindex:
Specify the index of the related Statistics entry, which ranges from 1 to 65535.

Choose an alarm variable to monitor. The
switch will monitor the specified variable in sample intervals and act in the set way when the
alarm is triggered. The default variable is revbyte.
revbyte
means total number of received bytes;
revpkt
means total number of received
packets;
bpkt
means total number of broadcast packets.
mpkt
means total number of
multicast packets;
crc-align
means packets that contain FCS Error or Alignment Error,
within a size of 64 to 1518 bytes;
undersize
means packets that are smaller than 64 bytes;
oversize
means packets that are larger than 1518 bytes;
jabber
means packets that are
sent when port collisions occur;
collision
means the collision times in the network segment;
