Service Manual

This mechanism copies all incoming or outgoing packets on one port and forwards (mirrors) them to another port.
The source port is the monitored port (MD) and the destination port is the monitoring port (MG).
Related Commands
deny — assigns a IP ACL filter to deny IP packets.
ip access-list standard — creates a standard ACL.
seq
Assign a sequence number to a deny or permit filter in an extended IP access list while creating the filter.
Syntax
seq sequence-number {deny | permit} {source [mask] | any | host ip-address}}
[count [byte] [dscp value] [order] [fragments] [threshold-in-msgs [count]
Parameters
sequence-number Enter a number from 0 to 4294967290. The range is from 0 to 65534.
deny Enter the keyword deny to configure a filter to drop packets meeting this condition.
permit Enter the keyword permit to configure a filter to forward packets meeting this criteria.
source Enter an IP address in dotted decimal format of the network from which the packet was
received.
mask (OPTIONAL) Enter a network mask in /prefix format (/x) or A.B.C.D. The mask, when
specified in A.B.C.D format, may be either contiguous or non-contiguous.
any Enter the keyword any to specify that all routes are subject to the filter.
count (OPTIONAL) Enter the keyword count to count packets the filter processes.
byte (OPTIONAL) Enter the keyword byte to count bytes the filter processes.
dscp (OPTIONAL) Enter the keyword dcsp to match to the IP DCSCP values.
order (OPTIONAL) Enter the keyword order to specify the QoS order for the ACL entry. The
range is from 0 to 254 (where 0 is the highest priority and 254 is the lowest; lower-order
numbers have a higher priority). If you do not use the keyword order, the ACLs have
the lowest order by default (
255).
fragments Enter the keyword fragments to use ACLs to control packet fragments.
threshold-in msgs
count
(OPTIONAL) Enter the threshold-in-msgs keyword followed by a value to indicate
the maximum number of ACL logs that can be generated, exceeding which the
generation of ACL logs is terminated with the seq, permit, or deny commands. The
threshold range is from 1 to 100.
Defaults
By default, 10 ACL logs are generated if you do not specify the threshold explicitly. The default frequency at which
ACL logs are generated is five minutes. By default, flow-based monitoring is not enabled.
