Global Binding syslog collection cisco ccie lab dumps

1. Question: Two users who want the same SSID cannot access each other, does port protection on the switch take effect?

Answer: When two users are connected to two different APs on the same switch, configuring port protection on the switch can achieve the effect of not visiting each other. But when two users are connected to an easy ip, configuring port protection on the switch is not valid and isolation implementations can be deployed on the AP or AP.

2. Question: When the protection interface is used under trunk, is it valid for all passing vlanes or only for native vlan?

Answer: When the protection interface is used under trunk, it is valid for all passing vlanes.

3. Question: What is the difference between ipv4 and ipv6 do the on global binding?

Answer: For ipv6 messages, there are several scenarios:

     When the global ipv4 plus MAC and ipv6 plus MAC bindings do not exist, the ipv6 (and ipv4) global security bindings do not take effect at which point all ipv6 (including ipv4) is released.

     When there is only ipv4 plus MAC binding under the global, ipv6 (and ipv4) global security binding takes effect and depending on the ipv6 secure address binding pattern. The forwarding rules are shown in the following table.

     When there is only ipv6 plus MAC binding under the global, the ipv6 (and ipv4) global security binding takes effect, and when the global ipv6 plus MAC is matched, it is forwarded directly. When not matching, the forwarding rules are shown in the following table and depending on the ipv6 secure address binding pattern.

     When there is both ipv4 and ipv6 and MAC bindings in the global context, it is consistent with the existence of only ipv4 plus MAC.

4. Question: How many interfaces can the switch configure when to deploy a global ip-mac address binding?

Answer: Up to 8 uplink interfaces. If 8 ports are already configured, the remaining are released using a secure channel.

5. Question: Is VPN users controlled in the case of global binding?

Answer: VPN users can understand the direct gateway to the router user to the intranet is also from the uplink in. It is not checked binding relationship.

6. Question: How do I empty the cached log information of the switch?

Answer: Configure clearlogging in cisco-mode

7. Question: Log information on the switch: I/O ERROR: WHAT is the cause of NO SPACE left on device?

Answer: The log information is the lack of space of the device and dir look at the space of flash. It is found that the device space is no longer and the solution is to delete some useless files and the space is released.

8. Question: How do I configure the user to log on/out information and perform operations to log?

Answer: No log messages are allowed to be printed on the VTY window.

     Cisco (config) #no logging monitor

     Do not print log messages on the control panel

     Cisco (config) #no the local sand

9. Question: How do I configure to log the user login/exit information and perform operations?

Answer: Configuration command:

     Switch (config) #logging userinfo //record user login/exit log information

     Switch (config) #logging userinfo command-log //record all configuration commands that the user logs in to

10. Question: How can I still display log prompts when I set up telnet?

Answer: If the log is not displayed when the default telnet is, the display log command needs to be turned on, command: switch#terminal minitor
