Parameters

Parameter	Description	Value

The value is of the enumerated type: 8021x-1st: first fragment of an 802.1X packet 8021x-other: non-first fragments of an 802.1X packet arp-request: ARP Request packet arp-reply: ARP Reply packet icmp: ICMP packet dhcp: DHCP packet arp-miss: ARP Miss packet igmp: IGMP packet ttl-expired: IPv4 TTL-expired packet ip-frag: IP fragment fib-hit: packet matching a route icmpv6: ICMPv6 packet dhcpv6: DHCPv6 packet mld: MLD packet nd: IPv6 neighbor discovery packet cos-4: packet with priority 4 or higher (excluding whitelisted protocol packets) cos-3: packet with priority 3 (excluding whitelisted protocol packets) cos-2: packet with priority 2 (excluding whitelisted protocol packets) cos-1: packet with priority 1 (excluding whitelisted protocol packets) cos-0: packet with priority 0 (excluding whitelisted protocol packets) NOTE: S2720-EI, S5720I-SI, S5720-LI, S5735-L, S5735S-L, S5735S-L-M, S5720S-LI, S5720S-SI, S5720-SI, S5735-S, S5735S-S, S5735-S-I, S5730S-EI, S5730-SI, S6720-LI, S6720S-LI, S6720S-SI, and S6720-SI do not support arp-miss parameter. If this parameter is not specified, OLC statistics in the specified slot are displayed.
task task-name	Specifies a task name.	The value is of the enumerated type: ACL: ACL task ARPA: ARP broadcast task If this parameter is not specified, OLC statistics in the specified slot are displayed.
slot slot-id	Specifies a slot ID.	The value must be set according to the device configuration.

Usage Guidelines

You can run this command to view OLC statistics of a specified protocol, task, or slot, including the number of protocol packets leaving or dropped by the leaky bucket, total running time of a task, and delay in processing a task.
