![]() ![]() Any MACs which appear on a VLAN are stored on the respective SOC MAC table. We have hit the 16K MAC limit in a production campus environment the Cisco docs and TAC have been pretty poor at discribing why!įrom what we have seen when an F2 only VDC is configured to operate at 元 and has SVIs present the MAC address limit is at its worst.Įach sequential 4 ports (port-group) share the same SOC. ![]() So in short are all MACs copied to all SoC's in the same VDC or only to those ones with shared VLANs. Would the second linecard see a copy of MAC addresses in vlans 10 to 50 if they only get trunked on ports on the 1st linecard? Would the second SoC on the 1st linecard see VLAN 10, 20 and 30 MAC addresses as well as 40 and 50 ? On another port I have vlans 10, 40 and 50 and on a further linecard port I have VLANs 60, 70 and 80 what MAC addresses are where ?Īre all MAC addresses from VLANs 10 - 80 on all cards or do the relevant card and it's SoC only hold the MAC addresses for the VLANs that exist on that cards trunks ? So if on card 1 I have a vPC carrying VLANs 10, 20 and 30. Does that mean that if I only use 1 VDC then the limit of MAC addresses across all linecards is 16K in total or as I have read somewhere else does limiting the VLANs on each port also reduce the MAC addresses held on each card? When I read further it says that MAC address tables are synchronized across ports in the same VDC. In the Cisco docs it says that the F2e card supports 16k MAC addresses per SoC and there are 12 per linecard implying a 192K MAC address limit PER linecard. ![]()
