Allows up on a single switch . 8 th 802.1q to ISL vlan mappings If the packets of the same data stream are sent in different paths, the IP packets may need to be re-queued when they reach the destination. This may reduce the forwarding performance of traffic such as VoIP , or if the packets arrive out of order, the quality of service will be degraded, packets may be discarded, and delay jitter will be added. Length The basic interaction process is as follows (the process described below is independent of the above diagram): port-security does not support etherchannel the port-channel interfaces The core layer switch SW2 also enables dhcp snooping . By default, all ports are untrusted . If the fast0/24 port of SW2 receives the dhcp packet carrying option82 , it is discarded. One of the solutions is to configure the fast0/24 port of SW2 as the trust interface.
