The number of entries allowed per ACL is hardware-dependent. Refer to your stack-unit
documentation for detailed specification on entries allowed per ACL.

Syntax
permit {source [mask] | any | host ip-address} [count [byte] ] [dscp value] [order]
To remove this filter, you have two choices:
• Use the no seq sequence-number command syntax if you know the filter’s sequence number or
• Use the no permit {source [mask] | any | host ip-address} command.

source
Enter the IP address in dotted decimal format of the network from which the
packet was sent.
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.
host ip-address Enter the keyword host followed by the IP address to specify a host IP address
or hostname.
count (OPTIONAL) Enter the keyword count to count packets processed by the filter.
dscp (OPTIONAL) Enter the keyword dcsp to match to the IP DCSCP values.
byte (OPTIONAL) Enter the keyword byte to count bytes processed by the filter.
order (OPTIONAL) Enter the keyword order to specify the QoS priority for the ACL
entry.
Range: 0-254 (where 0 is the highest priority and 254 is the lowest; lower
order numbers have a higher priority)
Default: If the order keyword is not used, the ACLs have the lowest order by
default (255).
