Team,
I am trying to dump the session table (show acl-plugin sessions) to view the
session info but don’t see any sessions getting created. Any input will be
helpful.
Plugin Version
vat# acl_plugin_get_version
vl_api_acl_plugin_get_version_reply_t_handler:133: ACL plugin version: 1.3
Following is the acl plugin configuration:
vat# acl_add_replace deny, ipv4 deny
vl_api_acl_add_replace_reply_t_handler:107: ACL index: 0
vat# acl_interface_set_acl_list sw_if_index 1 input 0 output 0
vat# acl_interface_set_acl_list sw_if_index 2 input 0 output 0
vat# acl_add_replace 0 permit src 192.168.1.10/32, permit
vl_api_acl_add_replace_reply_t_handler:107: ACL index: 0
vat# acl_dump
vl_api_acl_details_t_handler:193: acl_index: 0, count: 2
tag {}
