CPU utilization of F5OS on r2600
We have installed a new r2600 cluster and configured successful SNMP-monitoring. Here I must notice, that the CPU utilization of the F5OS with an average of more than 50% and peaks up to 90% is relatively high. The CPU utilization of the tenant looks fine with an average of around 15%. There is currently no active configuration on it nor any virtual server traffic passing the device. Is this a normal behavior, especially in comparison to the r5600 platform, where the F5OS CPU utilization average is at around 10%? Thank you! Regards, Stefan :)F5OS VLAN naming length restrictions
I must notice, that there seems to be a length restriction when creating VLANs on F5OS. I'm allowed to enter long names on F5OS-level without any warnings or errors, but when assigning them to a tenant, the name within the tenant will be truncated if its longer than 31 characters. It looks like this, means there is a suffix in the format of "-T<VLAN-ID>.0" On F5OS-level it looks like this: Is this a normal behavior? Can or will this be fixed? And are there any other such restrictions for other configuration items? For your reference, we are running F5OS 1.8.3 and BIG-IP 17.5.1.3. Thank you!

Introduction F5 rSeries & VELOS are rearchitected, next-generation hardware platforms that scale application delivery performance and automate application services to address many of today’s most critical business challenges. F5 rSeries & VELOS are key components of the F5 Application Delivery and Security Platform (ADSP). rSeries & VELOS rely on a Kubernetes-based platform layer (F5OS) that is tightly integrated with F5 TMOS software. Going to a microservice-based platform layer allows rSeries & VELOS to provide additional functionality that was not possible in previous generations of F5 BIG-IP platforms. The introduction of a new tenant-based architecture changes many things, including how you configure BIG-IP. Some of these changes affect the network configuration for Inline Layer 2 Services. By default, BIG-IP tenants only have a small set of internal MAC addresses available to them. However, Layer 2 Services (or Bridging) require additional MAC addresses. You must assign an adequate number of MAC addresses to what is called a “MAC pool”. A single Layer 2 Service requires two unique MAC addresses. The MAC Pool must have sufficient MAC addresses based on the number of Layer 2 Services you need. The following KB articles contain additional information on configuring MAC Pools on a BIG-IP rSeries or VELOS platform: K000133655: MAC address assignment in VELOS and rSeries systems K000135389: Configure the MAC Block Size for an existing BIG-IP tenant on the VELOS and rSeries systems Demo Video F5OS Configuration Let’s review the Network configuration on F5OS for a BIG-IP Tenant. From Network Settings select VLANs. Here you can see I have 6 Interfaces configured with VLANs. There’s a Lan VLAN for connectivity from the internal network to the BIG-IP. A Wan VLAN for connectivity from the BIG-IP to the internet. Then there are 4 “L2” VLANs configured to support two Inline Layer 2 Services with SSL Orchestrator. From the Interfaces screen you can associate the VLANs with the physical Interfaces. Next, allocate the VLANs to your BIG-IP Tenant. This is also where you configure the MAC Pool Size for your current BIG-IP Tenant. The MAC Pool can only be changed when the Tenant is not running. From Tenant Management > Tenant Deployments, you can stop the current Tenant if it is already running. Do this with caution during a change window or prior to deployment. Check the box next to the name of the Tenant you wish to configure, “big-ip-kevin” in this example. Then click Configure. Click OK to stop the Tenant When it’s stopped click the name of the Tenant to edit the configuration. Note the VLANs that are allocated to this BIG-IP Tenant: Find the section on MAC Data/MAC Block Size. Set the allocation to Small (8), Medium (16), or Large (32) depending upon your needs. I set mine to Medium. A Small allocation would be sufficient for this deployment but I want to leave room to add more Layer 2 Services in the future. Click Save & Close Click OK to update the configuration You can Deploy the Tenant now that the changes have been made Click OK to Deploy F5 BIG-IP Configuration Minimal configuration is needed on the BIG-IP since F5OS handles the underlying physical interfaces and VLANs. Check the status of the VLANs from Network > VLANs. From here we can see the VLAN configuration from F5OS is reflected in the BIG-IP. Define any Self IPs from Network > Self IPs Now we’re ready to configure SSL Orchestrator. In the interest of time, I will skip to the Network and Services configuration. From Services List click Add Service Double-click on Generic Inline Layer 2 Under Network Configuration click Add Select the L2 VLANs for this Inline L2 Service. Click Done. Click Add again and select the L2 VLANs for this Inline L2 Service. Click Done. It should look like the following: Click Save at the bottom For the Interception Rule select the Lan VLAN under Ingress Network and move it to the right. Click Save & Next at the bottom The Network configuration is now complete. SSL Orchestrator is configured with a Generic Inline Layer 2 Service that contains two Layer 2 “servers” Conclusion F5 rSeries & VELOS are hardware platforms that scale application delivery performance and automate application services to address many of today’s most critical business challenges. They are key components of the F5 Application Delivery and Security Platform (ADSP). In this article, you learned how to configure MAC Pools on rSeries and VELOS in order to create Layer 2 Inline Services with SSL orchestrator.

SNMP Monitoring/OIDs for rSeries
I'm currently configuring the required OIDs for monitoring our new rSeries, but I'm wondering if the provided MIBs contain all information? I'm searching especially the values from the GUIs dashboard for Memory Utilization and Storage Utilization like in the following screenshot: Also the mentioned "Base OS Version" and "Service Version" details seems to be not part of the MIB. I only found it under the OID .1.3.6.1.2.1.1.1.0 -> SNMPv2-MIB::sysDescr.0 = STRING: F5 rSeries-r5600 : Linux 3.10.0-1160.119.1.f5.1.el7_8.x86_64 : Appliance services version 1.8.3-23453. Where does the GUI render these information from? Is it possible to poll these details via SNMP as well? Any more details would be very helpful! Thank you! Regards, Stefan :)F5OS login with admin/root failed via console
Right now we have a new rSeries installed, which is currently only accessible via console cable. First login with default password was fine and changing password was also successful. Then I prepared the device with our default configuration including TACACS authentication. Also appliance-mode is enabled. All configurations were commited successfully. Now when I try to login in again, it failed with "login incorrect" error, but the password is definitely correct. What's the reason for this and how can I get access again? Or do I need to wait until the management port is up and TACACS server is reachable? Or how can I fully reset the device again? Power cycle and then interrupting the boot process? Is there a documentation available, how to perform this? Thank you! Regards, Stefan
Remove alerts showing r-series LCD/Dashboard.
Code is community submitted, community supported, and recognized as ‘Use At Your Own Risk’. Especially R5+ with 1.8.0+, may you will see unexpected "interface down" alerts. You could use this one-liner in rseries Bash.

R2600 device and tenant/partition configuration
Hello, I'm working with configuration on r2600 where is one tenant with multiple vlans. On tenant perspective I want to add each vlan to specific partition. How to do this in correct way for rSeries? There is a bug http://cdn.f5.com/product/bugtracker/ID1231889.html which says that all vlans need to be in Common partition. On vCMP or bare metal there was an option to create vlan in partition, add it to route domain and then configure all other things (IP, routes, etc). So - what is proper way? Where can I find F5 document?
