[ovs-discuss] Duplicated mirror packets are captured during recirclation

2024-03-11 Thread Zhangweiwei via discuss
Hi, I send an ICMP echo request packet from port tapVm71( IP: 1.1.70.1) to tapVm72( IP: 1.1.70.2) with CT, and there are two ICMP reply packets which are captured on tapVm72. We can see the ICMP reply packet sent by tapVm72 is mirrored twice within recirc_id(0) and recirc_id(0xe). This issue is

[ovs-discuss] Mirror: ovs-tcpdump cannot capture vlan packets on the port with tag

2024-03-06 Thread Zhangweiwei via discuss
Hi, I set tag 0 on port tapVm72 and tapVm71, and then send ping packets with vlan 100 from tapVm72 to tapVm71. But ovs-tcpdump cannot capture any packets with vlan on tapVm72. It seems that vlan check is failed in mirror_packet(), because tapVm72 is an access port and the vlan packets are droppe

[ovs-discuss] netdev-dpdk: The actual maximum packet size that can be transmitted for IP packets is MTU+4 when setting MTU for netdev-dpdk interface.

When using OVS-DPDK and setting MTU to 1500 for an Interface of type 'dpdkvhostuserclient', the maximum packet size that can be transmitted is 1522, as DPDK seems to have stripped off 4 bytes of CRC by default. However, in OVS the maximum packet size is 'MTU+RTE_ETHER_HDR_LEN + RTE_ETHER_CRC_LE

[ovs-discuss] bond: bond entry statistics overflow

2024-01-31 Thread Zhangweiwei via discuss
Hi, I encountered an issue while using OVS bond in balance-tcp mode. After performing down and up operations on bond members, the bond entry statistics displayed by ovs-appctl bond/show occured overflow. In addition to the statistics values issue, this also led to longer load balancing time for
