deployed with protected ports cannot communicate with each other.
If you configure pvlan on a layer-3 switch and the layer-3 switch is still a DHCP server, you need to configure a multi-layer switch hybrid port (that is, int VLAN *).
When configuring a DHCP server on a multi-layer switch, you must configure the VLAN interface address of the VLAN where the host is located, because DHCP uses UDP, dhcp on the vswitch finds the DHCP network segment corresponding to the VLAN Interface and assi
is performed on the specified port of the DP (designated port), and the port will not change. It will only be DP, which can prevent the newly added switch from becoming root, the port becomes a permanent DP. If the newly added vswitch wants to become root, its port cannot work until the new vswitch requests complete Rp. Show spanning-tree inconsistentport

to the CCSP course and listened to only one section. I understood why the OpenBSD team despised the people who spent money on VPN and firewall. Because hundreds of thousands of devices can do the same thing, a free operating system can do the same thing without being inferior to a professional device. If you use OpenBSD as a gateway routing system, you have to log on through ssh most times, instead of telnet. It should be noted that Cisco's IOS is a

First, prefaceIn the past week, the end of the CCSP game, which has a problem card I 9 hours, all kinds of debugging can not complete the mediation to the problem, so the pain decided to start the problem, this is part of the plan. In fact, based on the wrong understanding I wrote a number of topological sorting + dictionary order algorithm, but the collective unity GG, and finally found that, in fact, the design is not strictly the smallest dictionar
