yes, i will monitoring all the traffic on the vlan (vlan based span). the plattform is 3550-12G switch. what can i do for monitorig all the traffic in our campus lan?i can take only one port (physical) for source traffic monitoring rx and tx (both), so i have 12 ports for monitorig...what can i do, i dont find a solution!
In the example in the section Monitor VLANs with SPAN, traffic that enters and leaves the specified ports is monitored. The field Direction: transmit/receive shows this. The Catalyst 4500/4000, 5500/5000, and 6500/6000 series switches allow you to collect only egress (outbound) or only ingress (inbound) traffic on a particular port. Add the keyword rx (receive) or tx (transmit) to the end of the command. The default value is both (tx and rx).
set span source_port destination_port [rx | tx | both]
yes, in the configuration for vlan monitoring i can only monitor rx traffic, why again?. an other solution is monitoring the source gigabitinterfaces...on this way i can only 1 interface take for rx and tx (both) monitoring, but i have 8 gigabitinterface for monitoring...the cisco 3550-12G plattform dosent support more sourceports.
We have configured the outside and inside Interface with official ipv6 adresses, set a default route on outside Interface to our router, we also have definied a rule , which also gets hits, to permit tcp from inside Interface to any6.
In Syslog I also se...
