sFlow is a sampling technology for monitoring networks. You can monitor specified incoming data flows by including the
copy-sflow keyword in rules within an ACL applied to a device.
In order for sFlow to function, the sFlow
collector must be globally configured. For details, refer to the Extreme SLX-OS Monitoring Configuration Guide
.
-
Enter
configure terminal to access global configuration mode.
device# configure terminal
-
Enter the
mac access-list standard/extended command to create or access the ACL.
device(config)# mac access-list extended mac_ac12
-
In each rule for which you need to enable sFlow, include the
copy-sflow keyword.
device(conf-macl-ext)# seq 5 permit host 0022.3333.4444 host 0022.3333.5555 copy-sflow
device(conf-macl-ext)# deny host 0022.3333.7777 host 0022.3333.6666 copy-sflow
-
Apply the ACL that you created to the appropriate physical interface, specifying
in.
device(config)# interface ethernet 2/1
device(conf-if-eth-2/1)# mac access-group mac_acl2 in
