Read the bonding documentation, Chapter 5 Switch Configuration: https://www.kernel.org/doc/Documentation/networking/bonding.txt. Also, modprobe is not the correct place to configure bonding options, you should be using. "I have a 802.3ad bonded interface on our switched network, each port in the Network switches has one and only one NIC connected to it, however when the Network admin looks at the switch's port he sees multiple MAC addresses, the one from the bonded.

This option was added in bonding version 3.4.0. ad_user_port_key In an AD system, the port-key has three parts as shown below - Bits Use 00 Duplex 01-05. If ARP monitoring is used in an etherchannel compatible mode (modes 0 and 2), the switch should be configured in a mode that evenly distributes. Channel bonding (also known as NIC Teaming) enables multiple network interfaces to be joined together to form a single channel that gives higher bandwidth. cat /proc/net/bonding/bond0 Ethernet Channel Bonding Driver: v3.4.0-1 (October 7, 2008) Bonding Mode: fault-tolerance (active-backup) Primary. For our customer, we can only suggest them to reboot the server after change the bonding primary reselect method. But our document doesn't mention this. Example, I changed the primary reselect from failure to always. But the bonding status can be shown as: Ethernet Channel Bonding Driver: v3.4.0-2. [root@localhost]# /sbin/modprobe bonding.

Ethernet Channel Bonding Driver: v3.4.0 (October 7, 2008). Bonding Mode: fault-tolerance (active-backup). We are using LACP bonding in CRB (UDCC) so that networking can do maintenance on either side of the switch infrastructure without impacting our services. e.g. in Linux mode="1" means active/standby, but what we want in CRB is mode="4" which is an LACP bond...

When using the more explicit bonding configuration, the resultant configuration will resemble something like: Ethernet Channel Bonding Driver: v3.4.0-1 (Octobber 7, 2008) Bonding Mode: fault-tolerance (active-backup) Primary Slave: ethX (primary_reselect better) Currently Active Slave: ethX. MII Status:. To break down a network bonding in RHEL 5, 6 please follow the steps below. 1- Find the what Ethernet slaves are part of the bond. ex: # cat /proc/net/bonding/bond0 Ethernet Channel Bonding Driver: v3.4.0 Bonding Mode: load balancing (round-robin) MII Status: up MII Polling Interval (ms): 100 Up Delay. Useful information can be derived like the version of the Ethernet Channel Bonding Driver, the bonding mode used, bond interface status, each NIC port status and the MAC address for each NIC port.

Bonding is the same as port trunking. In the following I will use the word bonding because practically we will bond interfaces as one. But still...what is bonding? Bonding allows you to aggregate multiple ports into a single group, effectively combining the bandwidth into a single connection. Bonding also. #TYPE=BOND ### Do not change this.
