Fixes in 11.5.1

ID Number Description
ID 448299 The emulated IDE storage driver has been replaced with PV (para-virtualized) SCSI storage driver. PV SCSI driver gracefully handles disk I/O timeouts and recovers from them.

Fixes in 11.5.0

ID Number Description
ID 367759 On BIG-IP VE, modifying an interface's VLAN configuration from tagged to untagged, or untagged to tagged, can result in unavailability of traffic on that interface. Restarting the tmm with "bigstart restart tmm" will correct this condition, as will deleting and recreating the VLAN with desired tagging attributes.
ID 427415 AWS instances with core counts (vCPUs) higher than 4 is able to license and operate in the expected way.
ID 428612 "In order to make Intel SR-IOV work out-of-box, Intel VF's MTU has been reduced to 1500 in BIG-IP VE. VF's MTU has to be changed to be equal to or greater than its VLAN's MTU to support jumbo frame. A new feature is provided to make it happen. Steps to increase Intel VF's MTU in BIG-IP VE: - Append the following line to /etc/modprobe.d/f5-platform-virtual-applicance.conf file options unic max_mtu=<max_mtu_size> - reboot BIG-IP VE - OR, run: bigstart stop tmm rmmod unic modprobe unic bigstart start tmm"
ID 430655 Improved debugging on TMM to include DB variable provision.

There are no Virtual Edition-specific behavior changes specified for this release.

Behavior changes in 11.5.0

There are no known release-specific behavior changes.

Local Traffic Manager-Virtual Edition known issues

ID Number Description
ID 224507 When VE is deployed on VMware, the management port might not correctly reflect the uplink port speed of the vSwitch that it is connected to. This should have no adverse affects on actual management port traffic. Workaround:
ID 324960 "big3d daemon on Services screen (CR134045, ID 324960) The big3d daemon appears on the Services screen of the BIG-IP Configuration utility even though the daemon is not installed on the system." Workaround:
ID 346083 "When you remove an interface from all VLANs, and then add the same interface, the interface status remains UNINITIALIZED, and you can only access the system from the console. To recover, manually edit bigip_base.conf, deleting the entries and running the command: 'load sys config'. An entry appears similar to the following: net interface 1.3 { media-fixed 10000T-FD }" Workaround:
ID 351199 When importing an OVA into XenServer, CPU priority is not set. It is recommended that a higher priority be set on the VM. Using XenCenter, click on the General tab of the VM. Then click Properties. On the CPU and Memory tab, the VCPU priority should be configured at the highest value. Workaround:
ID 351367 "XenCenter OVF wizard's Run Operating System Fixups option blocks appliance import (ID 351367) When importing the OVA into XenCenter, make sure Run Operating System Fixups is unchecked." Workaround:
ID 351538 "F5 Networks strongly recommends that the host system use CPUs with AMD-V or Intel-VT technology. This might require adjusting the systems BIOS or Unified Extensible Firmware Interface (UEFI) configuration. For specific hypervisors, hardware assisted virtualization technologies might be required in order to boot BIG-IP VE. For detailed system requirements, see the hypervisor's documentation." Workaround:
ID 352456 Host-based time synchronization can last a few minutes in order to align the clocks. Workaround:
ID 352856 "If an SCF is migrated between BIG-IP VE running on non-similar hypervisor software, a validation error may prevent configuration loading. Loading the configuration ... BIGpipe interface creation error: 01070318:3: ""The requested media for interface 1.1 is invalid."" When this condition is encountered on BIG-IP Virtual Edition, configuration may be fixed for import by removing the entire line that contains ""media fixed"" statements for each interface." Workaround:
ID 358355 When deployed as a Microsoft Hyper-V virtual machine, BIG-IP VE must be configured with Static Memory Allocation. The use of Dynamic Memory Allocation is unsupported and might cause issues. Workaround:
ID 364704 Taking a snapshot of the virtual machine's memory often pauses the virtual machine and may produce undesired results. To correct this problem on VMware hypervisors, do not include the virtual machine's memory when snapshots are taken. Workaround:
ID 366403 After modifying the BIG-IP system configuration by adding or removing Network Interfaces, the interface numbering might appear out of order and NICs may appear that are no longer present. If the virtual interfaces on the BIG-IP VE system are changed after a binary MCPD database has been created, the system may not detect the change even after a subsequent reboot. To ensure that the system properly detects the new or removed interfaces, type the command "rm /var/db/mcpd*" at the BIG-IP VE command prompt, and reboot the system. TMM-to-vSwitch interface mapping can be viewed by comparing the MAC addresses of the interfaces displayed in the BIG-IP Configuration utility to those displayed in the hypervisors configuration. The interfaces may need a simple adjustment to map to the correct networks. Workaround:
ID 367862 Network Interface Port Mirroring is not supported by BIG-IP VE with this release. Workaround:
ID 370367 On BIG-IP VE only, changing the interface used by a VLAN from one to another might show degraded performance in the event that both interfaces are configured to participate on the same broadcast network. Restarting the TMM with "bigstart restart tmm" will restore performance and resolve the issue. Workaround:
ID 371458 On a XenServer Host, all interfaces are expected to show up as 100TX-FD within tmsh. All application traffic handling interfaces will be shown with a media speed of 100 and an Active Duplex of half in the GUI for this release. This speed rating is simply cosmetic and not actually reflective of the speeds and duplex for BIG-IP VE on a XenServer host. The actual link is a high speed internal connection via a Virtual Network Interface within the hypervisor at speeds greater than 100Mbps. Workaround:
ID 371631 BIG-IP Virtual Edition (VE) may incorrectly report the interface media duplex settings as none. The General Properties may show an incorrect Active Duplex setting when you navigate to Network :: Interfaces, and then click the interface. The output from the tmsh show network interface all-properties command may show incorrect information in the Media column. Running the command 'show net interface all-properties'. You are unable to confirm the current duplex setting of an interface. Workaround: To work around this issue, you can determine the interface media duplex setting for VE configurations not involving SR-IOV by running the following command: tmsh list net interface. Note: This workaround is valid only for VE configurations and only reports the VE's reported link state. A VM cannot determine any vSwitch's upstream link state via its own link state. VE knows about the link between it and the vSwitch, except in SR-IOV deployments, where there is no vSwitch and the link is direct.
ID 372540 Migration of BIG-IP VE, whether live or powered off, will commonly incur an innocuous warning message similar to this on vSphere hypervisors: Virtual Ethernet card 'Network adapter 1' is not supported. This is not a limitation of the host in general, but of the virtual machine's configured guest OS on the selected host." This message is benign and can safely be ignored. Workaround:
ID 374064 Import verification of the .ova may fail when using the XenCenter 5.6. OVA import wizard. It is suggested that XenCenter 5.6 users verify the .ova file signature as described on AskF5. Workaround:
ID 388118 For IPv6 to work on KVM using a macvtap interface, the IFF_ALLMULTI setting must be enabled on the host interface. This is done by using "ifconfig <name of interface>allmulti". Workaround:
ID 390961 Only Virtio NICs must be used for traffic and management. Workaround:
ID 394817 "VADC now supports CMP (that is, multiple TMMs running on the same box). For a rate limited license, the limit is divided by the number of TMMs, so each TMM is capped at a fraction of the total licensed limit. For example, if a 200M license with one connection has a throughput of 180Mbits/s before enabling CMP, then for two TMMs the expected throughput would be 90 Mbits/s, and with four TMMs, the expected throughput would be 45 Mbit/s." Workaround:
ID 399037 "BIG-IP Virtual Edition scans for up to ten NICs at boot time. If NICs are not present, a [FAILURE] message and log notification similar to ""notice network: Bringing up interface eth3: failed"" will be present in /var/log/boot.log. These are beneficial log messages that can be used to troubleshoot hypervisor virtual machine guest definitions and are otherwise innocuous. The systems mgmt NIC is commonly eth0 or the first derived interface scanned on a bus, commonly the first or zero NIC on a hypervisor. The tmsh command ""list net interface"" displays the systems detected NICs for traffic management services. All additional supported NICs beyond the mgmt interface will be used as tmsh interfaces." Workaround:
ID 404628 BIG-IP Virtual Edition hosted on XenServer cannot have more than six network interfaces configured in the virtual machine definition for this release of software. Workaround:
ID 413587 "The customer will see an extra interface when a Big-IP Virtual Edition is deployed on Citrix XenServer 6.1. This extra interface will have the same MAC address as the VE instance's management interface. The shell command 'ip list' will show one more interface that the user has configured through the hypervisor, and two of those interfaces shown will have the same MAC address." Virtual Edition deployed on Citrix XenServer 6.1 The management interface may be exposed to the TMM as a traffic interface. Workaround: A customer should use SR-IOV interfaces for VE instances deployed on Citrix XenServer 6.1.
