Makro Czech Republic and Metro Slovakia network
2001
I look after the network infrastructure for Makro Cash & Carry — covering head offices in Prague and Bratislava, wholesale stores, logistics platforms and drive-in collection points across the Czech Republic and Slovakia. This includes managing Cisco switches, routers and access points, troubleshooting operational issues, and designing and implementing changes.
- WAN network redesign for the Czech Republic and Slovakia (2006): analysis, topology mapping, inventory, and support for migrating branch offices to new connectivity providers,
- new core network for the Prague head office using Cisco Catalyst 6509 (2007–2008), migration from CatOS to IOS, redesigned DMZ,
- administrator authentication via TACACS+ and Wi-Fi user authentication via 802.1X/PEAP with Cisco Secure ACS,
- backup ISDN lines, HSRP, OSPF, VTP, GRE tunnels between the Czech Republic and Slovakia, QoS, and rolling out new VLANs across the network,
- aligning configurations with the standards of the parent Metro group,
- network preparation for an IP telephony pilot,
- management tooling: configuration archiving in RANCID, CiscoWorks LMS, NeDi, Cacti, custom software for monitoring switch port occupancy and utilisation, automated file transfers to the group’s SFTP server (mgi-xfer), and an internal wiki.
