Publication Date:  2012-07-25 Views:  51 Downloads:  0
Issue Description

Q:
MA5600T Version: V800R005C03B118
Customer found that after the command "active configuration" for the second time, a configuration line is lost.
This is the sequence:
1. Initially the line in the configuration file is: 
igmp profile profile-index 0 program-list 0-674,694-695,718-921 watch
2. Initial configuration/Empty database -> load configuration -> active configuration
After the reboot the configuration line becomes: 
igmp profile profile-index 0 program-list 7,10-12,16-18,21,32-37,48-53,64-70,80-85,96-99,101-102,112-115,117-118,128-170,200-205,209-212,232-237,248-263,298-300,302-304,306,327,330-332,336-338,341,352-357,368-373,384-390, watch
igmp profile profile-index 0 program-list 400-405,416-419,421-422,432-435,437-438,448-490,520-525,529-532,552-557,568-583,618-620,622-624,626,640-644,656-660,672-674,694-695,718-721,738-741,758-921 watch
3. If we issue "active configuration" command for the second time: 
We get the only following line after reboot, the first line is lost:
igmp profile profile-index 0 program-list 400-405,416-419,421-422,432-435,437-438,448-490,520-525,529-532,552-557,568-583,618-620,622-624,626,640-644,656-660,672-674,694-695,718-721,738-741,758-921 watch
This happens because of the symbol "," in the end of the first line: "igmp profile profile-index 0 program-list 7,10.... 384-390, watch". OLT cannot process this line correctly because of this symbol.
