Symptom
- 端口统计中的“接收传入错误”计数器递增：
Hardware interface counters read from CPU: -------------------------------------------------------------------------------- bytes received 3940489261880 bytes transmitted 5132423471269 packets received 2101567189 packets transmitted 2537857620 receive incoming errors 270410 receive discarded 0 receive errors 117415 packets dropped 0 -------------------------------------------------------------------------------- > show interface ethernet1/1 | match errors receive incoming errors 270410 receive errors 117419 > show interface ethernet1/1 | match errors receive incoming errors 270577 receive errors 117643
- 计数器“rcv_fifo_overrun”也递增：
> show system state filter sys.s1.p1.detail | match fifo
sys.s1.p1.detail: { 'pkts1024tomax_octets': 0x143a89288, 'pkts128to255_octets': 0xe0d1eada, 'pkts256to511_octets': 0x327bed35, 'pkts512to1023_octets': 0x1c5c06ca, 'pkts64_octets': 0x68e22d0e, 'pkts65to127_octets': 0x3890c2de, 'rcv_fifo_overrun': 0x42072, }
> show system state filter sys.s1.p1.detail | match fifo
sys.s1.p1.detail: { 'pkts1024tomax_octets': 0x143c4720f, 'pkts128to255_octets': 0xe0ea87af, 'pkts256to511_octets': 0x3281c784, 'pkts512to1023_octets': 0x1c5ebc47, 'pkts64_octets': 0x68ec11d7, 'pkts65to127_octets': 0x3895aaa4, 'rcv_fifo_overrun': 0x4208f, }
Environment
- Firewall
- Panorama
- PAN-OS
- A 开关连接到Firewall或者 Panorama
Cause
- “rcv_fifo_overrun”计数器的增加可能表明连接的设备不支持流量控制。
- 在没有流量控制的情况下，任何线速波动（例如突发/微突发、瞬态利用率峰值、广播\mcast 风暴）可能会增加“收到的传入错误”和“rcv_fifo_overrun”计数器。
Resolution
必须在连接到交换机的交换机上配置流量控制PAN-OS设备。 请与交换机供应商确认如何配置此功能。
