关于VOIP上配置端口安全的问题

本帖最后由 小乔 于 2011-9-24 16:41 编辑

QUESTION 232
When you enable port security on an interface that is also configured with a voice VLAN, what is the
maximum number of secure MAC addresses that should be set on the port?
A. No more than one secure MAC address should be set.
B. The default will be set.
C. The IP phone should use a dedicated port, therefore only one MAC address is needed per port.
D. No value is needed if the switchport priority extend command is configured.
E. No more than two secure MAC addresses should be set.
Answer: B
Section: Mixed Practice Questions 2
Explanation/Reference:
http://www.cisco.com/en/US/docs/switches/lan/catalyst2950/software/release/12.1_14_ea1/configuration/
guide/swvoip.html
•When you enable port security on an interface that is also configured with a voice VLAN, you must set the
maximum allowed secure addresses on the port to at least two.
最少要配置2个。所以,B选项错的。

那么到底是怎么样啊?又没有试验环境!!

这道题我也查过一些资料和外国的论坛,大家一致认为这个是cisco的bug,这个答案没错,但是这里打印错误,正确的是:The default should be set. 而 不是will be set. 这里要强调的是默认情况max mac address应该被设定。
