Seq (For Ipv6 Acls) - Dell C9000 Series Reference Manual

Version
9.3.0.0
Usage Information When the configured maximum threshold is exceeded, generation of logs is stopped.
When the interval at which ACL logs are configured 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 configured
threshold is exceeded, it is re-enabled for this new interval.
If ACL logging is stopped because the configured threshold is exceeded, it is re-
enabled after the logging interval period elapses. ACL logging is supported for standard
and extended IPv4 ACLs, IPv6 ACLs, and MAC ACLs. You can configure 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 flow-based monitoring for a monitoring session by entering the
flow-based enable command in the Monitor Session mode. When you enable this
capability, traffic with particular flows 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
specified traffic instead all traffic on the interface. This feature is particularly useful
when looking for malicious traffic. It is available for Layer 2 and Layer 3 ingress and
egress traffic. You may specify traffic 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).

Commands

seq (for IPv6 ACLs)

Assign a sequence number to a deny or permit the filter in an IPv6 access list while creating the filter.
C9000 Series
Syntax
seq sequence-number {deny | permit} {ipv6-protocol-number | icmp |
ip | tcp | udp} {source address mask | any | host ipv6-address}
{destination address | any | host ipv6-address} [operator port
[port]] [count [byte]] [log [interval minutes] [threshold-in-msgs
[count]] [monitor]
To delete a filter, use the no seq sequence-number command.
Description
