Hi Peeps - hoping that someone with a v7.6.0.2 (NB52x0) appliance, for which they are sure that 1 Gb NIC bonding is working, would be willing to show the output of 'linkaggregation show' - please?

Got some appliances and whilst bonding looks to have been set-up, I hoping to spot differences between a known working show, and what I can see with the appliances that I'm looking at.

I'm unable to show what I can see - as no connectivity out. So hoping someone can show me what they see. Please. Thanks.

Here you go, this is the output of 2.6.1 from our Symantec lab with IP address and all the mac addresses removed. The readout it the same as 2.6.0.2/7.6.0.2

Thank you - I'll check/compare tomorrow...

also make sure your network infrastructure is supporting the bonding type you're configuring in your appliances.you have to setup the same type of bonding as configured on your switches you're connected.

the different types of bonding are (see below) the same type has to be setup on your switch and appliance.

Round-robin (balance-rr): Transmit network packets in sequential order from the first available network interface (NIC) slave through the last. This mode provides load balancing and fault tolerance.
Active-backup (active-backup): Only one NIC slave in the bond is active. A different slave becomes active if, and only if, the active slave fails. The single logical bonded interface's MAC address is externally visible on only one NIC (port) to avoid distortion in the network switch. This mode provides fault tolerance.
XOR (balance-xor): Transmit network packets based on [(source MAC address XOR'd with destination MAC address) modulo NIC slave count]. This selects the same NIC slave for each destination MAC address. This mode provides load balancing and fault tolerance.
Broadcast (broadcast): Transmit network packets on all slave network interfaces. This mode provides fault tolerance.
IEEE 802.3ad Dynamic link aggregation (802.3ad)(LACP): Creates aggregation groups that share the same speed and duplex settings. Utilizes all slave network interfaces in the active aggregator group according to the 802.3ad specification.
Adaptive transmit load balancing (balance-tlb): Linux bonding driver mode that does not require any special network-switch support. The outgoing network packet traffic is distributed according to the current load (computed relative to the speed) on each network interface slave. Incoming traffic is received by one currently designated slave network interface. If this receiving slave fails, another slave takes over the MAC address of the failed receiving slave.
Adaptive load balancing (balance-alb): includes balance-tlb plus receive load balancing (rlb) for IPV4 traffic, and does not require any special network switch support. The receive load balancing is achieved by ARP negotiation. The bonding driver intercepts the ARP Replies sent by the local system on their way out and overwrites the source hardware address with the unique hardware address of one of the NIC slaves in the single logical bonded interface such that different network-peers use different MAC addresses for their network packet traffic.

Just following up, how was the comparison?

VOX

Could someone show the output from a working linkaggregation show...
