Mediant 500 E-SBC
Parameter Description
overall (re-assembled) packet size, and not to the size of each
fragment.
Byte Rate
CLI: byte-rate
[AccessList_Byte_Rate]
Defines the expected traffic rate (bytes per second), i.e., the allowed
bandwidth for the specified protocol. In addition to this field, the
'Burst Bytes' field provides additional allowance such that momentary
bursts of data may utilize more than the defined byte rate, without
being interrupted.
For example, if 'Byte Rate' is set to 40000 and 'Burst Bytes' to
50000, then this implies the following: the allowed bandwidth is
40000 bytes/sec with extra allowance of 50000 bytes; if, for example,
the actual traffic rate is 45000 bytes/sec, then this allowance would
be consumed within 10 seconds, after which all traffic exceeding the
allocated 40000 bytes/sec is dropped. If the actual traffic rate then
slowed to 30000 bytes/sec, then the allowance would be replenished
within 5 seconds.
Burst Bytes
CLI: byte-burst
[AccessList_Byte_Burst]
Defines the tolerance of traffic rate limit (number of bytes).
The default is 0.
Action Upon Match
CLI: allow-type
[AccessList_Allow_Type]
Defines the firewall action to be performed upon rule match.

"Allow" = (Default) Permits these packets

"Block" = Rejects these packets
Match Count
[AccessList_MatchCount]
(Read-only) Displays the number of packets accepted or rejected by
the rule.
The table below provides an example of configured firewall rules:
