[Issue ]
All cameras are very slow
[Analysis]
- The cctv server have gig card / and was connecting to Ethernet port so we advised to move the server to gig interface but same issue happened .
- We checked the access and core switches for the cameras slowness issue and we found high output utilization on all interfaces :
-A lot of multicast discarded :
- We enabled the igmp-snooping under the VLAN 175 (CCTV VLAN) on core switch as CCTV use multicast :
[vlan-175]igmp-snooping enable
- And now traffic is normal
[Root cause]
- Server connected to Ethernet ports .
- IGMP-snooping was not enabled under the vlan
[Solution]
1- Confirmed that the server connected properly to gig interfaces .
2- Enable IGMP-snooping under vlan .
