I see people in CISCO2950 configure ACL, I would like to blunt the second floor of the three-tier agreement on how to handle equipment? Please enlighten you heroes, the table below : Access-list 111 permit any any icmp
Access-list 111 permit ip any host 61.72.*.*
Access-list 111 permit ip host 61.72.*.*any
Access-list 111 permit ip host 61.72.*.*any
Access-list 111 permit ip host 61.72.*.*any
Access-list 111 permit ip host 221.23.*.*any
111 deny ip any any access-list
Int vlan 1
Ip 111 in access-group
111 out ip access-group
Exit
Interface vlan 1
Ip address ********
Exit
Ip default-gateway *******
2950 can be connected into the network MAC certain restrictions, and if so, it may limit the number of MAC ACL can be set up in 2950 on the MCL can be set up based on the MAC. Only version of the software. ? ? ? Faint path where the device is the first of two three-tier layer ah faint! ! ! You instead of the seven layer OSI Reference Model layer and access layer device pool equipment confused the core layer equipment Awesome, the landlord also need to understand the concept of Layer 7 Jimmy! ! Faint path where the device is the first of two three-tier layer ah faint! ! ! CISCO2950 pure switcher, it seems they do not mention what router also has no routing function? ? ?
Is it pure two-story, I would like to ask the equipment can handle IP packets?
Can handle the ACL Sorry I did not look carefully at what the catalyst is generally cisco switches. I go home on a 2950 test can be used if the acl Switch#? as follows :
Exec commands :
Create a temporary Access-entry access-enable
Create a temporary Access-entry access-template
Archive manage archive files
Cd Change current directory
Clear Reset functions
Clock Manage the system clock
She subsystem Mar
Configure Enter configuration mode
Connect Open a terminal connection
Copy Copy from one file to another
Killing Debugging functions (see also 'undebug')
Delete Delete a file
Dir List files on a filesystem
Disable Turn off privileged commands
Disconnect Disconnect an existing network connection
Dot1x Dot1x Exec Commands
Enable Turn on privileged commands
Erase erase a filesystem
Exit Exit from the EXEC
Format a filesystem format
Fsck a filesystem fsck
--More--
Create a temporary Access-entry only access-enable Create a temporary Access-entry access-template
This 2
If the IOS can support the 2950G Switch (configure) #? Configure commands :
Aaa Authentication, Authorization and Accounting.
Add an access list entry access-list
Alias Create command alias
Arp Set a static ARP entry
Define a banner banner Login
Boot boot Commands
Buffers Adjust system buffer pool parameters
Cdp Global CDP configuration subcommands
Class-map Configure QoS Class Map
Configure time-of-day clock clock
Cluster cluster configuration commands
Mar She Subsystem
Set a default command to its defaults
Default values default-value character-bits
Define interface range macro definition
To do run exec commands in configure mode
Dot1x Dot1x Global Configuration Commands
Generate a configuration compatible with older downward-compatible-config
Software
Enable Modify enable password parameters
End Exit from configure mode
However, I configured a useless role of the ACL CISCO2950 and is a three-Switch IOS version there is no effect of the order
2950 switcher is not the ACL but can support IP-based MAC ACL Only three switches and routers to support IP ACL. IP equipment is not recognized because the second floor.
Okay I have committed such a mistake, but not a guilty one or two old.
I commend look at the "TCP Xiangxie"
