Version Description
9.13.0.1P1 Introduced peTenGigE interface support on the C9010.
9.9(0.0) Introduced on the C9010.
Usage
Information
If you do not attach an ingress or egress access-list to an interface, no information displays and you
return to the DELL# prompt.
Example
Dell# show ip access-lists out
Standard Egress IP access list first
seq 5 permit any count bytes (0 bytes)
seq 10 deny any count (0 packets)
Standard Egress IP access list five
seq 5 permit any
Standard Egress IP access list four
seq 5 permit any count bytes (0 bytes)
seq 10 deny any count (0 packets)
Standard Egress IP access list second
seq 5 permit host 1.1.1.1 count bytes (0 bytes)
Extended Egress IP access list ten
seq 5 permit tcp any eq 1 any
seq 10 deny ip any host 11.11.11.11 count (0 packets)
Extended IP ACL Commands
The following commands configure extended IP ACLs, which in addition to the IP address, also examine the packet’s protocol
type.
The C9000 supports both Ingress and Egress IP ACLs.
When an ACL is created without any rule and then applied to an interface, ACL behavior reflects an implicit permit.
NOTE: Also refer to the Commands Common to all ACL Types and Common IP ACL Commands sections.
deny
Configure a filter that drops IP packets meeting the filter criteria.
C9000 Series
Syntax
deny {ip | ip-protocol-number} {source mask | any | host ip-address}
{destination mask | any | host ip-address} [count [bytes]] [dscp value]
[order] [monitor] [fragments] [log [interval minutes] [threshold-in-msgs
[count]] [monitor]
To remove this filter, you have two choices:
● Use the no seq sequence-number command if you know the filter’s sequence number.
● Use the no deny {ip | ip-protocol-number} {source mask | any | host ip-
address} {destination mask | any | host ip-address} command.
Parameters
ip Enter the keyword ip to configure a generic IP access list. The keyword ip
specifies that the access list denies all IP protocols.
ip-protocol-
number
Enter a number from 0 to 255 to deny based on the protocol identified in the IP
protocol header.
source Enter the IP address of the network or host from which the packets were sent.
