Command History
This guide is platform-specic. For command information about other platforms, see the relevant Dell Networking
OS Command Line Reference Guide.
Version Description
9.8(0.0P5) Introduced on the S4048-ON.
9.8(0.0P2) Introduced on the S3048-ON.
9.7(0.0) Introduced on the S6000–ON.
9.4(0.0) Added support for ow-based monitoring on the S4810, S4820T, S6000, Z9000, and
MXL 10/40GbE Switch IO Module platforms.
9.3.0.0 Added support for logging of ACLs on the S4810, S4820T, Z9000, and MXL 10/40GbE
Switch IO Module platforms.
Usage Information
When the congured maximum threshold is exceeded, generation of logs is stopped. When the interval at which
ACL logs are congured to be recorded expires, the subsequent, fresh interval timer is started and the packet
count for that new interval commences from zero. If ACL logging was stopped previously because the congured
threshold is exceeded, it is reenabled for this new interval.
If ACL logging is stopped because the congured threshold is exceeded, it is reenabled after the logging interval
period elapses. ACL logging is supported for standard and extended IPv4 ACLs, standard and extended IPv6 ACLs,
and standard and extended MAC ACLs. You can congure ACL logging only on ACLs that are applied to ingress
interfaces; you cannot enable logging for ACLs that are associated with egress interfaces.
You can activate ow-based monitoring for a monitoring session by entering the ow-based enable command in
the Monitor Session mode. When you enable this capability, trac with particular ows that are traversing through
the ingress and egress interfaces are examined and, appropriate ACLs can be applied in both the ingress and
egress direction. Flow-based monitoring conserves bandwidth by monitoring only specied trac instead all trac
on the interface. This feature is particularly useful when looking for malicious trac. It is available for Layer 2 and
Layer 3 ingress and egress trac. You may specify trac using standard or extended access-lists. 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).
seq ether-type (for Extended MAC ACLs)
Congure an egress lter with a specic sequence number that lters trac with specied types of Ethernet packets. This command is
supported only on 12-port GE line cards with SFP optics. For specications, refer to your line card documentation.
NOTE
: Only the options that have been newly introduced in Release 9.3(0.0) and Release 9.4(0.0) are described here. For a
complete description on all of the keywords and variables that are available with this command, refer the topic of this command
discussed earlier in this guide.
Syntax
seq sequence-number {deny | permit} ether-type protocol-type-number
{destination-mac-address mac-address-mask | any} vlan vlan-id {source-mac-
address mac-address-mask | any} [count [byte]] [order] [log [interval minutes]
[threshold-in-msgs [count]] [monitor]
To remove this lter, use the no seq sequence-number command.
Parameters
log (OPTIONAL) Enter the keyword log to enable the triggering of ACL log messages.
