我和我的团队似乎没有让 Catalyst 3560 交换机上的 NetFlow 正常工作。让我告诉你配置:
flow exporter NETFLOW-EXPORTER
destination 10.10.10.12
source Vlan100
transport udp 2055
!
!
flow record NETFLOW-RECORD
match ipv4 tos
match ipv4 protocol
match ipv4 source address
match ipv4 destination address
match transport source-port
match transport destination-port
match interface input
collect interface output
collect counter bytes long
collect counter packets long
!
!
flow monitor NETFLOW-MONITOR
record NETFLOW
exporter NETFLOW
statistics packet protocol
statistics packet size
cache timeout active 60
interface range GigabitEthernet 0/1-52
ip flow ingress
ip flow egress
ip flow monitor NETFLOW-MONITOR input
ip flow monitor NETFLOW-MONITOR output
如您所见,我们正处于添加几乎所有内容的地步。出口商似乎仍然没有向目的地发送任何东西:
Flow Exporter NETFLOW-EXPORTER:
Description: User defined
Export protocol: NetFlow Version 9
Transport Configuration:
Destination IP address: 10.10.10.12
Source IP address: 10.10.100.254
Source Interface: Vlan100
Transport Protocol: UDP
Destination Port: 2055
Source Port: 61154
DSCP: 0x0
TTL: 255
Output Features: Not Used
目标:10.10.10.12 正在运行配置此交换机的 PRTG 实例。SNMP 信息似乎工作得很好,只是 NetFlow 不会显示任何内容。PRTG 上的配置应该没问题(IP 和端口匹配)
有任何想法吗?
提前致谢 :)
