Problem Description
An IGMP issue has been discovered with the internal switch of the GigE chassis that causes the cards to lose connectivity with the network. In a fully populated chassis this may occur randomly about once per day.
Background
The GigE chassis is a 16 slot chassis that has two slots taken up by an internal Gigabit Ethernet switch. The other 14 ports may be occupied by up to 14 CIVS-SG1XXXX single channel encoder cards. The application of the chassis is 14 ports of video encoding with Gigabit Ethernet connectivity to the video server.
An IGMP issue has been discovered with the internal switch that causes the cards to lose connectivity with the network. In a fully populated chassis this may occur randomly about once per day.
Problem Symptoms
Cards losing connectivity with the network.
Workaround/Solution
Workaround:
Power cycling the card restores network connectivity.
Solution:
The recommended solution is to replace the GigE chassis with an FE chassis. The FE chassis does not contain an internal switch but provides
for direct Ethernet connectivity to each individual CIVSSG1XXX card. Used together with a Cisco 2960 1RU switch, the CIVS-SG1XXX cards
in an FE chassis are individually connected with Ethernet cabling to the 2960 switch providing the same
functionality as provided by the GigE chassis. One advantage of this configuration is that since the FE chassis does not contain an internal switch,
all 16 slots are available for CIVS-SG1XXX cards providing the capacity for up to 16 cards rather than 14.
Installations of GigE chassis that are not experiencing loss of network connectivity issues do not need to be replaced.
