While looking for a 16- or 24-port gigabit ethernet switch with at least 6 VLANs and port mirroring (packet duplication to a monitoring port), I came up with three candidates (there are more): Cisco SRW2024, Netgear GS724T and HP ProCurve 1810G
I need any VLAN to be capable of at least one full GigE-communication between two ports that is not disturbed by any other traffic.
What I can't figure out is: Are these switches capable of switching multiple full-load GigE-links that sum up to 6xGigE? In the past this was known as the backplane capacity (especially when stacking multiple switches to form a giant broadcast domain) but now some don't give any information (HP in the case of the J9450A) and the others state "Nonblocking, store-and-forward switching mechanism" or even "Bandwidth: 48 Gbps".
Is it common knowledge that GigE switches handle anything you send to them as long as no single-link capacity is overloaded?
Best Answer
All three of the links you provided specify 48Gbps of throughput/bandwidth/switching-capacity if you read their specs. So yes, you'll be fine for full 1/2Gbps-to-1/2Gbps port-to-port linking with any of them.
