Permit Udp - Dell Force10 Z9000 Reference Manual

The C-Series and S-Series cannot count both packets and bytes; when you enter the count
byte options, only bytes are incremented.
The monitor option is relevant in the context of flow-based monitoring only. For more
information, refer to
Most ACL rules require one entry in the CAM. However, rules with TCP and UDP port operators
(for example, gt, lt, or range) may require more than one entry. The range of ports is configured
in the CAM based on bit mask boundaries; the space required depends on exactly what ports
are included in the range.
Example
An ACL rule with a TCP port range of 4000–8000 uses eight entries in the CAM.

permit udp
Configure a filter to pass UDP packets meeting the filter criteria.
C-Series, E-Series, S-Series, Z-Series
Syntax permit udp {source mask | any | host ip-address} [operator port
[port]] {destination mask | any | host ip-address} [dscp]
[operator port [port]] [count [byte] | log] [order] [monitor]
[fragments]
To remove this filter, you have two choices:
Port Monitoring.
– creates an extended ACL.
– assigns a permit filter for IP packets.
– assigns a permit filter for UDP packets.
• Use the no seq sequence-number command if you know the filter's sequence
number.
• Use the no permit udp {source mask | any | host ip-address}
{destination mask | any | host ip-address command.
