7.3.2 TRex commands example
Using these commands the configuration is:
1. NAT learn mode (TCP-ACK)
2. Delay of 1 second at start up (-k 1). It was added because ASA drops the first packets.
3. Latency is configured to ICMP reply mode (--l-pkt-mode 2).
Simple HTTP:
[bash]>sudo ./t-rex-64 -f cap2/http_simple.yaml -d 1000 -l 1000 --l-pkt-mode 2 -m 1000 -- ←-
learn-mode 1 -k 1
This is more realistic traffic for enterprise (we removed from SFR file the bidirectional UDP traffic templates, which (as described
above), are not supported in this mode).
Enterprise profile:
[bash]>sudo ./t-rex-64 -f avl/sfr_delay_10_1g_asa_nat.yaml -d 1000 -l 1000 --l-pkt-mode 2 - ←-
m 4 --learn-mode 1 -k 1
