Brocadecom

The news is public: Broadcom is acquiring Brocade, my employer. Official announcement here, and some (unofficial) commentary here. What’s happening, and what does it mean for me?

VRF-Aware SNMP on Brocade VDX

SNMP was not designed with VRFs in mind. Querying the routing table via SNMP did not take into account the idea of having multiple routing tables. But clearly it’s something people want to do, so some clever engineers figured out how to shoe-horn VRF contexts in. This week a customer asked me how to query […]

Don’t Trust Hotel Currency Conversion

Experienced travelers will already know this, but it bears repeating: Don’t trust your hotel to perform currency conversions for credit card transactions. They will rip you off.

When the IPv6 Data Changes, so Should Your Opinion

Sky UK recently completed their rollout of IPv6. The uptake statistics are quite remarkable. If you think that people don’t have IPv6-capable devices, or that their home routers can’t handle IPv6…you really need to look at the data, and re-think your opinion.

netmiko support for Brocade ICX and MLXe

netmiko is a “Multi-vendor library to simplify Paramiko SSH connections to network devices,” written by Kirk Byers. It doesn’t solve all of your pain with dealing with CLI-only network devices, but it tries to at least take away the low-level hassle of setting up a connection, and handling variations with things like enable mode, line-breaks, […]

VRRP Skew Time (and always be learning…)

It’s funny how you can work with something for years, but miss a small detail. This week I learnt about Skew Time for VRRP. The reason for it is completely obvious once you think about it, but for some reason the detail had escaped me for all these years. VRRP Hellos VRRP sends out a “hello” […]

Travel Badge of Shame

All frequent flyers strive to the top tier of their program. Qantas Platinum, BA Gold, KrisFlyer Elite Gold, United Premier 1K. They all want that extra level of benefits, those extra upgrades. But a former manager said: “You don’t really want to be on the top tier. You want to be on the tier just below, […]
