Introduction\u00a0 \u00a0 \u00a0\u00a0<\/strong><\/p>\n

We would like to announce the upgrade of the version of Comware running on our DC Distributor FroDos. This follows on from the recent upgrade of all customer FroDos during September and the start of this month.<\/p>\n

This blog entry aims to answer the majority of questions that this work will raise. Please, however, feel free to contact the Networks team with any further questions at\u00a0networks@it.ox.ac.uk<\/a><\/p>\n

Why?<\/strong><\/p>\n

As part of ongoing maintenance it is essential that we keep our FroDo software\u00a0up to date. The new version of software being deployed addresses a number of vulnerabilities and bugs.\u00a0This takes us from R2612H01 to R2702 for these devices.<\/p>\n

Impact<\/strong><\/p>\n

All DC Distributor FroDos are HPE 5940\u2019s running in an IRF pair. As a result, we can use the HPE In Service Software Update (ISSU) feature which\u00a0aims to minimise\u00a0impact to traffic passing through the FroDo pair as it is upgraded.<\/p>\n

The DC distributors do run a variety of customer annexe connections into the DC sites Frodo and this information is listed within\u00a0Huggin<\/a>. Just enter the name or frodo number. Any customers who do not have an aggregated annexe connection across both devices will be affected\u00a0as the single device they connect to reloads. The reload time for a HPE 5940 is ~10 minutes.<\/p>\n

Finally, we have recently migrated several services from the old service spine onto pairs of DC distributors. With that in mind I have provided a list, in upgrade order, of the central services that are hosted on each device.<\/p>\n

It is important to remember that we have resilience in the form of IRF as well as the service being provided from two distinct dcdist FroDos. However, as with all upgrades, there is an element of risk and therefore the services themselves should be considered at risk during the upgrade window.<\/p>\n
