- Security Policies – Logging (SRX Traffic Logs) – Stefan Herbst details how to configure logging on the Juniper SRX appliances. The logging itself seems very powerful but I have a question, where can I see a log entry if my Ethernet port went down? The logging has an emense amount of detail for all the different services and subsystems but it seems to come up short (or I haven’t figured out how to configure it yet) how to just get the basics such as OSPF down, Ethernet down, tunnel down, Ethernet up, tunnel up, OSPF up, etc. without turning on debug and being overwhelmed with data.
- Bandwidth requirements for long distance vMotion – Duncan Epping tries to answer Kurt Bales question around vMotion bandwidth requirements. I personally didn’t realize there was a bandwidth requirement but I did know that there was a RTT requirement of 5ms or less between the ESX hosts.

Avaya Ethernet Routing Switch 4000 Software Release v5.6.2
Avaya has released software v5.6.2 for the Ethernet Routing Switch 4000 Series.
Here’s the list of fixes;
- wi01026335 100FX SFP, Display: The Avaya 100FX SFP (AA1419074-E6) is now correctly displayed as a supported SFP in variations of the switch which can support slow speed SFPs.
- wi01054301 801.2X, RADIUS Health Check: The RADIUS health check password is now correctly encrypted with the server key when sending a reachability packet to the RADIUS server.
- wi01047335 802.1X, Clear MAC Address: When issuing the clear mac-address-table address
command against an EAP/NEAP MAC address it is now correctly removed from the Layer2 MAC Address table.
- wi01049393 802.1X, RADIUS Reachability, ASCII Config: RADIUS Reachability username is now correctly output when generating an ASCII configuration file.
- wi01046960 802.1X, RADIUS Reachability, IPv6, Log Messages: Log messages related to RADIUS Server reachability are now correctly displayed when RADIUS servers are configured for IPv6.
- wi01032441, wi01032439 802.1X, RADIUS VLANs (RAV), DHCP Requests, Wrong VLAN: When the switch boots, DHCP traffic is now correctly blocked until EAP/NEAP authentication starts. Previously DHCP request would be forwarded by the switch before EAP authentication, which could result in the end device obtained an IP Address which may be in the wrong VLAN is RADIUS Assigned VLANs (RAVs) are used.
- wi01055405Diags, New Agent Software: The diagnostics software has been updated to correctly recognise 5.7.0 and later agent code releases.
- wi01053526 Diags, PoE+, 4850GTS, Shared Ports: An diagnostics internal loopback error which occurred when some devices were connected to the shared ports (47 or 48) on the 4850GTS or 4850GTS-PWR+ has now been addressed.
- wi01055434 Diags, PoE+, Warm Boot: The diagnostics now correctly keeps PoE+ disabled during a warm boot process until control is passed to the agent software.
- wi01034775 EDM, ECMP: The Maximum Path value in the ECMP configuration tab for EDM can now be changed from the default value of 1 and successfully applied to the switch.
- wi01029886 EDM, Help File, ASCII Config: EDM Help file path is now correctly output when generating an ASCII configuration file.
- wi01042035 EDM, Password Display: EDM now correctly shows console/web/telnet passwords when operating as a single unit or a stack.
- wi01042931 EDM, PoE Port status: EDM now correctly displays PoE status when requesting output for a large number of PoE ports, rather than displaying “Request timed out” error.
- wi01006349 EDM, Username, Software Exception: An issue which existed when a username longer than 2 characters was entered into EDM has now been addressed. The switch will no longer product a software exception.

Avaya Ethernet Routing Switch 4850GTS-PWR+
I’m currently doing an in-depth evaluation of the ERS 4850GTS-PWR+ for my organization as we prepare to expand one of our facilities to meet the growing needs of the surrounding community. The ERS 4850GTS-PWR+ provides 48 10/100/1000 802.3at PoE+ & 2 SFP ports plus 2 SFP+ ports & HiStack ports. You can order the switch with a 300W or 1000W power supply depending on your needs. The switch chassis will accept a redundant 300W or 1000W hot swappable power supply.
I was provided 2 evaluation units, ERS 4826GTS-PWR+ by our (value added) reseller. Interestingly enough I had some issues running software release 5.6.0 when I would reboot (soft) the stack of 2 switches. In the majority of cases the stack would not recover after the reboot until I power (cold) cycled both switches. That issue appears to have been resolved in 5.6.1 software as I have yet to observe that problem since I upgraded. I’m testing the switch with a number of desktops, laptops, IP phones, wireless access points, etc. I have yet to find an 802.3at device that I can use to test with in the office, although I’m hoping that Motorola has some 802.3at access ports that I can test.
The ERS 4800 has the ASICs that can support Avaya’s VENA architecture where as the ERS 5500 and 5600s won’t be able to support VENA.
