A Large Number of TC Packets Received on an S6700 Switch Causes High CPU Usage and Protocol Flapping |
When an S6700 switch receives a large number of TC packets, it frequently updates MAC and ARP entries. The CPU of the switch needs to process a large number of ARP request and ARP-Miss packets, so the CPU usage becomes high. In addition, the processing of other protocol packets is affected, causing flapping of those protocols. |

By default, the AR router discards the ICMP packets with the TTL value of 1. Tracert packets are ICMP packets with the TTL value of 1. Therefore, when a tracert packet reaches the AR router, the AR router discards the tracert packet and does not respond. As a result, a tracert error occurs. |

Link Aggregation Cannot Be Implemented Between an S5700 and a Non-Huawei Device |
An S5700 switch is connected to a Cisco Catalyst 3560 switch through bundled links. The S5700 uses the standard Link Aggregation Control Protocol (LACP) defined by IEEE to implement link aggregation, whereas the Cisco switch supports both LACP and Cisco proprietary Port Aggregation Protocol (PAgP). If the Cisco switch uses the PAgP protocol, link aggregation cannot be implemented between the two switches. |
