问题如下：
两台cisco 3750E做的堆叠。IOS版本如下：
core-down#show version

目前的问题是：
我输show ip traffice后，在IP statistics下面，
bad hop count和not a gateway 这两项不正常。每秒钟都会增加几十个计数。
core-down#show ip traffic
IP statistics:
Rcvd: 432317279 total, 97435362 local destination
1165 format errors, 1339 checksum errors, 311477316 bad hop count
79 unknown protocol, 23001384 not a gateway
0 security failures, 0 bad options, 43 with options
Opts: 0 end, 0 nop, 0 basic security, 0 loose source route
0 timestamp, 0 extended security, 0 record route
0 stream ID, 0 strict source route, 43 alert, 0 cipso, 0 ump
0 other
请教一下大家，这种现象一般会是哪些情况会造成此影响？有没有什么解决办法？
-------------------------------------------------------------------最新进展--------------------------------------------------------------------
我通过命令:debug ip error detail ，将有错误的包信息从日志当中复制出来（以下是debug信息）：
从debug信息来看，应该是有大量的UDP包导致 bad hop count 和not a gateway 快速增加。
从UDP的内容来看，LLMNR，NBNS 大量充斥网络。
问一下大家这种问题怎么处理啊？？
还有就是很多到目标地址:192.168.1.1这个是什么鬼流量。我们内网都没有192.168.1这个网段。。。。
